Fri Apr 7 13:43:31 PDT 2017 Ken Pizzini <ken@gnu.org>
* bc/configure.ac: update dc version to 1.4.1;
update dc copyright year list
Fri Apr 7 13:14:41 PDT 2017 Phil Nelson <philnelson@acm.org>
* bc/Makefie.am: Do a different fix for parallel make issues.
Fri Apr 7 00:11:49 PDT 2017 Ken Pizzini <ken@gnu.org>
* dc/eval.c, dc/numeric.c: take more care to never pass
a sign-extended char to the <ctype.h> isXXX() functions.
Thanks to a NetBSD compiler warning for flagging this.
Thu Apr 6 22:47:46 PDT 2017 Phil Nelson <philnelson@acm.org>
* bc/execute.c: More tweaks to fix for read() problems.
* bc/Makefile.am: Attempt to fix parallel make problems.
Thu Apr 6 16:39:25 PDT 2017 Phil Nelson <philnelson@acm.org>
* bc/execute.c: Correct leading space problem caused by last fix.
* bc/configure.ac: version to 1.07.1
Thu Apr 6 15:37:22 PDT 2017 Phil Nelson <philnelson@acm.org>
* bc/execute.c: Correct input_char for base 36 input.
* doc/bc.1: Update documentation for base 36 input.
* doc/bc.texi: Update documentation for base 36 input.
Thu Apr 6 14:26:27 PDT 2017 Ken Pizzini <ken@gnu.org>
* dc/eval.c: The 'Q' command "fix" of 2016-09-24 was incorrect.
It fixed a reported bug, but introduced a regression for other
existing (and correct) code. Let's try this again (sigh).
Thu Apr 6 13:11:15 PDT 2017 Ken Pizzini <ken@gnu.org>
* dc/dc.c: bah, nevermind; just re-disovered commit of
Oct 26, 2013 where the setvbuf() was rendered unnecessary
by introduction of explicit fflush()-es.
Thu Apr 6 13:11:15 PDT 2017 Ken Pizzini <ken@gnu.org>
* dc/dc.c: re-instate setvbuf() call that got lost
Mon Jan 16 14:30:00 PDT 2017 Phil Nelson <philnelson@acm.org>
* Updated copyright to 2017.
Sun Oct 23 16:38:05 PDT 2016 Ken Pizzini <ken@gnu.org>
* dc/eval.c: dc_system() already eats up to (and including)
a trailing newline, so don't fall-through in dc_evalstr()'s
DC_SYSTEM case to DC_COMMENT's skip_past_eol() call,
as that would unexpectedly require eating a second newline.
Thanks to David José for noticing and reporting the bug.
Thu Oct 20 03:11:43 PDT 2016 Ken Pizzini <ken@gnu.org>
* doc/dc.texi: fix some typos.
Mon Oct 17 00:28:50 PDT 2016 2016 Ken Pizzini <ken@gnu.org>
* doc/dc.1, doc/dc.texi: document the new default-to-zero
of the 'l' command.
Mon Oct 17 00:02:11 PDT 2016 Ken Pizzini <ken@gnu.org>
* doc/dc.1, doc/dc.texi: be more careful in specifying how
the precision of the result of the "v" (square root)
command is determined.
Thanks to David José for pointing out that the old text
underspecified this.
Sun Oct 16 23:43:05 PDT 2016 Ken Pizzini <ken@gnu.org>
* dc/stack.d: return a 0 (zero value; instead of reporting an error)
for the "l" command when the named register stack is empty.
Thanks to David José for the suggestion. (This is a useful default
value, and make GNU dc more compatable with BSD dc and Bell Labs
version 7 dc.)
Wed Sep 28 13:24:50 PDT 2016 Ken Pizzini <ken@gnu.org>
* dc/eval.c, doc/dc.1, doc/dc.texi: update copyright dates
Sat Sep 24 16:04:01 PDT 2016 Ken Pizzini <ken@gnu.org>
* dc/dc.c, dc/eval.c: yesterday's fix for 'Q' created a
new bug for the 'q' command; this fresh (and simpler!)
fix does the right thing. (Thanks again to Paul Rayner.)
Fri Sep 23 22:49:17 PDT 2016 Ken Pizzini <ken@gnu.org>
* dc/dc.c: don't prematurely exit from stack-unwinding 'Q'
command
* dc/eval.c: ensure that DC_FAIL API value does not
collide with any internal dc_status code
* doc/dc.1, doc/dc.texi: clarify that 'Z' command reports
on digits in decimal representation in number (as opposed
to ambiguous, perhaps "o"base, digits).
* (Bugs reported by Paul Rayner; thanks.)
Mon Feb 29 15:56:00 PST 2016 Phil Nelson <philnelson@acm.org>
* Makefile.am, bc/Makefile.am: update to not include
libmath.h in distribution.
* configure.ac: update copyright with 2016
Mon Feb 29 13:06:00 PST 2016 Phil Nelson <philnelson@acm.org>
* bc/Makefile: Add $(LIBBC) as dependency to fbc so
libmath.h gets correctly built. sbc also needed it.
Mon Feb 29 12:05:00 PST 2016 Phil Nelson <philnelson@acm.org>
* bc/util.c, bc.y: Fix two memory leaks submitted to
Gentoo by Bruce Dubbs.
Tue Jan 19 22:10:10 PST 2016 Phil Nelson <philnelson@acm.org>
* bc/{execute.c, load.c, main.c, proto.h, scan.l, storage.c, util.c},
lib/number.c: Update copyrights, remove old style function
declarations, remove _PROTOTYPE macros, update to GPL V3.
Various other code cleanups.
Mon Jan 11 14:01:32 PST 2016 Ken Pizzini <ken@gnu.org>
* doc/dc.texi: fix typo (reported by Avinash Sonawane)
Mon May 11 16:40:31 PDT 2015 Ken Pizzini <ken@gnu.org>
* dc/stack.c: catch the case of an empty value on top of
a register stack (i.e., the stack entry is first created by
an array store on a previously unallocated register)
as a normal run-time error, rather than an abort() condition.
(Bug reported by Hanno Böck, who found it during fuzz testing.)
Mon Jan 26 22:30:00 PST 2015 Phil Nelson <philnelson@acm.org>
* bc/execute.c, load.c, scan.l, storage.c: Extend input
base to allow for base 36 with Z being the largest
input digit. Now, ZZZZZ will be the largest 5 digit
number given the allowable bases.
Mon Jan 26 21:34:00 PST 2015 Phil Nelson <philnelson@acm.org>
* various: updated copyright on all GPL licence comments.
Mon Jan 19 00:03:05 PST 2015 Ken Pizzini <ken@gnu.org>
* News: brought up-to-date for dc-1.07 release
* README: bump relase number
* bootstrap.sh: let the autotools give us as much guidance as they can
* configure.ac: modernize, based on autotools' -Wall suggestions;
update copyright years; GPL version 3; use URL to get copy of GPL,
instead of snail-mail address; version bump (for both dc and bc);
simplify the libedit/readline/flex cross-check logic
* dc/eval.c: update copyright years
Thu Nov 27 22:17:17 PST 2014 Ken Pizzini <ken@gnu.org>
* dc/eval.c: dc_evalstr() incorrectly used len-1, to omit counting the
closing ']', unconditionally, even when string parsing terminated
prematurely (end-of-string reached before closing ']' was found).
This is wrong in general, and painfully wrong when len==0.
(Bug reported by Hanno Böck, who found it during fuzz testing.)
Fri Oct 31 13:50:18 PDT 2014 Ken Pizzini <ken@gnu.org>
* dc/eval.c: dc_evalstr() was inappropriately/prematurely returning
when the top-of-stack was a number. (Bug reported by Saito Takaaki.)
Sun Sep 7 15:20:29 PDT 2014 Ken Pizzini <ken@gnu.org>
* dc/eval.c: the '!' command was incorrectly interacting with stdin
rather than fp (the current input stream) when reading the
shell command to be executed. (Bug reported by Dario Niedermann.)
Sat Oct 26 14:54:37 PDT 2013 Ken Pizzini <ken@gnu.org>
* doc/dc.1, doc/dc.texi: Updated copyright dates.
Sat Oct 26 14:54:37 PDT 2013 Ken Pizzini <ken@gnu.org>
* doc/dc.1, doc/dc.texi: Documented the "R" (rotate stack) command.
Sat Oct 26 14:39:10 PDT 2013 Ken Pizzini <ken@gnu.org>
* dc/dc-proto.h, dc/dc.c, dc/eval.c, dc/misc.c, dc/numeric.c,
dc/stack.c, dc/string.c:
Explicitly flush output, instead of requesting line buffering,
as the user may be emitting a prompt (without a trailing newline)
within an inferior process. Also, clean-up/simplify related code.
Fri Jun 29 13:14:18 PDT 2012 Ken Pizzini <ken@gnu.org>
* dc/eval.c dc/stack.c, dc/dc-proto.h:
Implement 'R', general stack rotation command
Thu Mar 7 21:55:47 PST 2013 Phil Nelson <phil@cs.wwu.edu>
* configure.ac, bc/Makefile.am, dc/Makefile.am, lib/Makefile.am:
Update automake definitions for newer versions of automake.
Tested with version 1.13.1.
Tue Nov 2 11:09:00 2010 Phil Nelson <phil@cs.wwu.edu>
* bc/{bc.y, execute.c, load.c, main.c, proto.h, scan.l,
util.c}: Add a bc_exit() routine that resets the editline
state in one place to exit. Removed editline state reset
in other places.
Sun Mar 21 11:42:16 2010 Ken Pizzini <ken@gnu.org>
* dc/eval.c: take a more nuanced approach to handling SIGINT
Thu May 22 17:28:07 2008 Ken Pizzini <ken@gnu.org>
* All: update copyright statements and license statements:
the code is now released under GPL-3, and documentation
under FDL-1.2.
* configure.in, Makefile.am, bootstrap.sh; h/* lib/* gnulib/* m4/*:
import portability code via gnulib-tools
* bc/bc.y, bc/sbc.y, bc/execute.c, bc/load.c, bc/main.c, bc/proto.h,
bc/scan.l, bc/util.c: detect, report (if possible), and exit with
error if any I/O errors are encountered
* doc/dc.texi: clean-up preamble (using more modern texinfo macros)
Mon Sep 4 19:27:49 2006 Ken Pizzini <ken@gnu.org>
* configure.in: re-factor how version numbers are handled; add errno.h
and strtol() checks; add doc-texi-ver.incl output
* bc/bcdefs.h: Prefer <string.h> over <strings.h>
* bc/execute.c, bc/load.c, bc/main.c, bc/proto.h, bc/scan.l,
bc/storage.c, bc/util.c, bc/warranty.c: De-lint some with "const"
declarations, "static" declarations, and un-shadowing a few global
variables and functions
* dc/dc.c: add "static" keyword on flush_okay() function declaration,
just for good hygene
* dc/numeric.c: Reworked to avoid breaking C99 type-punning rules
Wed Jun 14 08:21:17 2006 Ken Pizzini <ken@gnu.org>
* dc/numeric.c (dc_int2data): rework code so that C99 compilers
stop whining about the type punning
* dc/dc.c (flush_okay): add "static" keyword as a matter of good
coding hygene
Sun Jun 11 21:40:37 2006 Ken Pizzini <ken@gnu.org>
* doc/bc.1: strip release version information which is not being
automatically kept up-to-date
* doc/dc.1: don't capitalize Dc or DC
Sun Jun 11 09:07:26 2006 Ken Pizzini <ken@gnu.org>
* doc/bc.texi, doc/dc.texi, doc/texi-ver.incl.in, doc/Makefile.am:
make version text in texinfo-based documentation auto-derive from
configure.in
* configure.in: update to use more modern automake/autoconf
directives; factor out version numbers so that AC_SUBST and
AC_OUTPUT kcan be used to create doc/texi-ver.incl
* doc/Makefile.am: automake does (now) have a mechanism to
auto-include declared man pages in the dist tarball, so
remove FIXME block
Sun Jun 11 03:04:18 2006 Ken Pizzini <ken@gnu.org>
* lib/Makefile.am: testmul, specialnumber, multidigits.h are
autogenerated by special request (only), and "make clean" should
remove them
* lib/testmul.c: CLOCKS_PER_SEC is typically a "long" value, so make
test_time wide enough to hold it; add missing #include directives
* lib/number.c: silly warning clean-up:
+ declare rt_warn() and rt_error() to take a CONST char* first
argument
+ neither _bc_rec_mul() nor _bc_simp_mul() use the full_scale
argument, so remove it in the function definitions and invocations
+ some C libraries define an index() function; use a different index
variable name to avoid gratuitous namespace shadowing
Sun Jun 4 13:56:58 2006 Ken Pizzini <ken@gnu.org>
* doc/dc.texi: document new DC_LINE_LENGTH variable; mention
traditional dc's handling of P with a numeric input
* dc/dc.c (flush_okay, main): make code detecting and handling
write errors cleaner
Sun Jun 4 12:26:00 2006 Phil Nelson <phil@cs.wwu.edu>
* bc/main.c: Make sure 3 is the minimum line length.
* doc/bc.1, doc/bc.texi: Document the BC_LINE_LENGTH of 0 feature.
Sun Jun 4 04:41:28 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c (main): fflush() isn't enough: also check that fclose()
does not return an error before exiting with EXIT_SUCCESS
Sun Jun 4 04:15:15 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c, dc/eval.c: detect, report (if possible), and exit with error
if any I/O errors are encountered
Sun Jun 4 02:27:41 2006 Ken Pizzini <ken@gnu.org>
* bc/main.c, bc/util.c: allow a BC_LINE_LENGTH of zero as a
special-case, meaning "don't ever wrap lines"
* dc/numeric.c, configure.in: add support for a DC_LINE_LENGTH
variable, with a value of zero meaning "don't ever wrap lines"
Fri May 5 18:45:17 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c (try_file): S_ISREG() test was inverted! :-(
(how very embarrassing)
* configure.in: the "if test" -> "case" conversion in the last commit
translated the handling of flex incorrectly; fixed
* src/scan.l: readline versions 4.2 and up give their own prototype
for readline() in readline.h, which conflicts with the one that is
in scan.l, so just do without the prototype in scan.l (if someone
needs to backport to a very old version of readline, they should be
able to handle adding the prototype back in themselves)
* doc/bc.texi: use of @var{} in @item causes capitalization on output,
which is wrong, and furthermore the use of @var{} for e() and j() is
also inconsistent with how the other math functions are formatted
Sat Apr 29 05:02:15 2006 Ken Pizzini <ken@gnu.org>
* configure.in: The "true" branch of AC_ARG_WITH needed to
be conditionalized on the value of $withval (thanks to Mike
Frysinger of Gentoo for pointing this out); prefer using
"case" over "if test" in shell string-match conditionals;
make use of AC_HELP_STRING; added copyright block; clean
out old "dnl"'d directives
Sat Apr 29 04:02:23 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c (try_file): fix typo in S_ISFIFO conditional
* doc/bc.1, doc/bc.texi, doc/dc.1, doc/dc.texi: make some
formatting clean-up (minor)
Wed Apr 26 15:38:32 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c (try_file): rework special-file detection so that
friendlier error messages can be given for the most common
error of this class (i.e., the "dc directory" typo).
Thu Apr 20 17:45:46 2006 Ken Pizzini <ken@gnu.org>
* configure.in: Newer versions of flex (such as ver. 2.5.33)
don't seem to like an argument of "-I8" anymore ("option `I'
doesn't allow an argument"), so split that into "-I -8".
Wed Mar 29 05:09:14 2006 Ken Pizzini <ken@gnu.org>
* dc/string.c, dc/misc.c, dc/stack.c, dc/dc.c, dc/eval.c, dc/array.c:
Make splint (http://www.splint.org/) happier by making all
comparisons to 0 and NULL explicit, and adding some explicit casts
that aren't strictly necessary. (But I'm omitting from this commit
various splint annotations that just serve to make the code ugly.)
Tue Mar 28 13:36:00 2006 Phil Nelson <phil@cs.wwu.edu>
* bc/util.c: Move code so size checks are before use.
* doc/bc.1: Quote .IP argument.
Tue Mar 28 12:09:38 2006 Ken Pizzini <ken@gnu.org>
* dc/dc.c (try_file): Added file type detection to ignore some
special files (particularly directories and block files), because
several people have asked that a typo for "cd" not fail silently.
* configure.in: add detection of fstat() to determine how the
above detection should be implemented.
Wed Mar 15 9:50:00 2006 Phil Nelson <phil@cs.wwu.edu>
* lib/getopt.c: Added a define to disable/enable
gettext support. May need to be deleted later
when gettext is fully supported.
Mon Mar 13 13:57:00 2006 Phil Nelson <phil@cs.wwu.edu>
* bc/bc.y: Remove second call to lookup() in a rule.
Removes a free'd twice bug.
Sat May 28 05:42:01 2005 Ken Pizzini <ken@gnu.org>
* doc/dc.1, doc/dc.texi: add verbage about the need to use
upper-case letters for ibase>10 (bug reported by "TJIC").
Fri May 20 ??:??:?? 2005 Ken Pizzini <ken@gnu.org>
* lib/getopt.c, lib/getopt1.c: Update to more recent versions.
Fri May 27 09:19:21 2005 Ken Pizzini <ken@gnu.org>
* dc/eval.c: abstract out skip_past_eol() function to handle comments
Fri May 27 07:30:52 2005 Ken Pizzini <ken@gnu.org>
* dc/numeric.c (dc_numlen), doc/dc.1, dc.texi: correct Z command
to match historical meaning
Fri May 27 06:54:19 2005 Ken Pizzini <ken@gnu.org>
* dc/eval.c: ignore trailing comments in tail-recursion detection
* dc/eval.c, doc/dc.texi: finally fix dc to trap interrupts,
aborting pending macros but not exiting
Fri May 27 03:37:30 2005 Ken Pizzini <ken@gnu.org>
* dc/numeric.c: Address Debian bug #221781: values exceeding
a C "long" don't play well with k/i/o/a/Q/:/; commands.
Adding a diagnostic, and returning a "more bogus" value than
zero, for this situation.
Thu May 26 09:03:57 2005 Ken Pizzini <ken@gnu.org>
* dc/eval.c:
1) fix tail recursion to also work for 'x' and '?' commands
2) fix tail recursion to ignore trailing spaces in the current
invocation string when determining if tail recursion is
appropriate
3) remove a couple of misleading and/or meaningless comments
4) add documentation for stdin_lookahead, since the code is far
from transparent about its purpose and usage
5) simplify ibase conditional by rearranging branches
Wed May 25 21:20:08 2005 Ken Pizzini <ken@gnu.org>
* dc/array.c dc/dc-proto.h dc/dc-regdef.h dc/dc.c dc/dc.h
dc/eval.c dc/numeric.c: whitespace cleanup

update FSF address in copyright notices
Wed May 25 19:39:46 2005 Ken Pizzini <ken@gnu.org>
* dc/stack.c: If a register is used for an array, its corresponding
stack could be auto-created in the DC_UNINITIALIZED state; handle
this situation gracefully. Thanks to Ben Collerson
(http://bur.st/~benc/) for the bug report.
Wed Dec 31 07:26:00 2003 Phil Nelson <phil@cs.wwu.edu>
* Makefile.am: add depcomp

* dc/dc-proto.h dc/dc.c dc/eval.c: add tail-recursion optimization
* dc/numeric.c: clean up handling of conditional includes/defines;
editorial fix to comment; trivial (indentation, mostly) clean-up of
out_char() function [gratuitious; commit was accidental and I'm
adding this note to a replacement log message]
* dc/misc.c: fixed spelling and grammatical errors in comment
* dc/dc-regdef.h: simplify the handling of UCHAR_MAX/DC_REGCOUNT
defaults
Thu Apr 17 16:25:35 2003 Phil Nelson <phil@cs.wwu.edu>

Fri Jan 19 10:33:13 2001 Phil Nelson <phil@cs.wwu.edu>
* bc/{main.c,execute.c}: Don't use stdio calls in signal

* lib/testmul.c: #ifdef out a declaration matching #ifdef out
code.
Mon Jul 31 07:01:42 2000 Ken Pizzini <ken@gnu.org>
* dc/numeric.c: use of the "n" command can cause a number to be printed
without a trailing newline, which would cause the column counter to
fail to be reset and result in inappropriately wrapped numeric outputs.
Fixed by always clearing the column counter before outputting each number.
* dc/stack.c: if a stack is used without ever using the correspondingly
named register, it is perfectly legitimate for the register to be
uninitialized; added an "else if" to handle this case without aborting.
* dc/eval.c: updated the comment explaining the restrictions
on the | command to better reflect reality.
* doc/dc.texi: update the FSF office address in the copyright notice

Tue Feb 8 08:54:19 2000 Phil Nelson <phil@cs.wwu.edu>
* doc/bc.1, bc/util.c: Removed "multiply digits"

Tue Jan 6 09:15:04 PST 1998 Ken Pizzini <ken@halcyon.com>
* h/version.h: dc is now up to version 1.1.5.
* dc/eval.c, dc/numeric.c, doc/dc.texi, doc/dc.1: once again
changed the behavior of the 'P' command with a numeric argument
to make it more general. It now dumps out the *whole* number
(or rather, the whole of its positive integer portion) as a
byte stream. (For small values this is still the same as 'aP'.)
* dc/dc-proto.h, dc/dc.h, dc/eval.c, dc/misc.c, dc/numeric.c,
dc/stack.c, dc/string.c: Changed most uses of dc_boolean to
either dc_discard or dc_newline, and instances of DC_TRUE and
DC_FALSE to appropriate instances of DC_TOSS, DC_KEEP, DC_NONL,
or DC_WITHNL so that the code self-documents a little better.
Sun Jan 4 15:39:46 PST 1998 Ken Pizzini <ken@halcyon.com>
* dc/eval.c, doc/dc.texi, doc/dc.1: Changed the functionality
of the 'P' command, and added the 'n' command. Due to
a quirk of the implementation of traditional dc, some
people have come to expect that the 'P' command on a
numeric argument in the range of 1 to 99 should output
the corresponding character, despite the fact that this
usage can have very weird results for numbers outside
that range. This functionality is why the 'a' command
was introduced last March, but people really want it to
"just work" without needing to use the 'a' command.
Bowing to this demand, the 'P' command now does the
equivalent of "aP" if the argument is numeric, and the
'n' command has been added to support the previous
functionality of the 'P' command.
* dc/misc.c, dc/eval.c, dc/stack.c, dc/dc-proto.h:
Changed prototype for dc_print(). It now additionally
takes two flags, newline_p and discard_p, which it
passes through to dc_out_num() and dc_out_str() as
needed.
* h/version.h: dc is now up to version 1.1.4.
Sat Sep 27 13:48:53 1997 Ken Pizzini <ken@halcyon.com>
* h/version.h: dc is now up to version 1.1.3.
* dc/stack.c, dc/array.c, dc/dc-proto.h, doc/dc.texi, doc/dc.1:
It has come to my attention that, though undocumented,
traditional dc stacked its arrays in parallel with the
stacking of simple registers. I have now duplicated
this functionality.
* dc/dc.c, configure.in: line-buffer dc's output if setvbuf()
is supported. This was requested to simplify using dc as
an inferior process under emacs.
Fri Sep 26 19:56:15 1997 Ken Pizzini <ken@halcyon.com>
* dc/dc.c: fixed bug reporting address for --help.

Fri Apr 8 14:16:37 1994 Phil Nelson (phil@cs.wwu.edu)
* Makefile: Change the distribution to include libmath.h.dist
which is a copy of libmath.h that has the compiled libmath.b.
Sun Feb 13 01:08:14 1994 Phil Nelson (phil@cs.wwu.edu)
* execute.c: Change the string quote characters to be more like
C. \a => alert (bell) \b => backspace and added \q => ".

Tue Feb 16 10:06:45 1993 Phil Nelson (phil at cs.wwu.edu)
* util.c: (call_str, arg_str) added a function call_str that
correctly produces the string of argmuent types for a function
call. arg_str produced them in the reverse order. This
eliminated the need for the "comma" argument to arg_str, which
was removed.
* bc.y: changed the calls to arg_str to have only one parameter
in the function definition rule and replaced the call to arg_str
with call_str in the function call rule.

GNU coding standards.
Tue Jul 7 21:09:07 1992 Phil Nelson (phil at cs.wwu.edu)
* (const.h, bc.y, util.c) Added code so that when the math
library is loaded, redefinition of any math library function
will not cause the other functions to quit working correctly.
Before this change, redefining a(x) would cause s(x) and c(x)
to quit working and redefining s(x) would cause c(x) to quit
working.
Wed Jul 1 14:35:29 1992 Phil Nelson (phil at cs.wwu.edu)
* (libmath.b) Changed the calculation of scale for computing
e(x) and l(x). This provides a little more accuracy in the
last digit at the expense of a little speed.
* (Test/checklib.b) Changed tests to be parameterized and test
more values.
Thu Jun 25 09:22:59 1992 Phil Nelson (phil at cs.wwu.edu)
* (configure) changed the script from looking in the
include directory for a .h file to asking cc (gcc) to
find the .h file. This will allow better detection
of include files available to the C compiler.
Wed Jun 24 22:11:37 1992 Phil Nelson (phil at cs.wwu.edu)
* (bc.y) Added a warning for the "last" variable.

* (bc.1) Documented the use of dot (.) for "last".
* (Makefile) Added an easy method for adding extra defines for
use during the compile. Set DOT_IS_LAST as a standard
extra define.

* Changed the name of math.h to libmath.h to avoid conflict
with /usr/include/math.h. Changed all references to math.h
to libmath.h in all files.
* (configure) Changed the test for long strings accepted by
cc to not include libmath.h and thus not need to distribute
a file that is generated by the system.
* (Makefile) Changed PREFIX, BINDIR, LIBDIR, and MANDIR to
lower case.
Tue Mar 3 10:16:07 1992 Phil Nelson (phil at cs.wwu.edu)

* (load.c) Added termination to "load_code" to ignore code
after an error has been found.
* (scan.l) Changed the check for NUL characters in STRING tokens
(before the close quote) to work correctly. Also added code to
report illegal characters in a more readable output format.
* (bc.1) Added the exclusion of NUL characters from strings in
the "differences" section and updated date of last change.
* (const.h) Changed BC_MAX_SEGS to 16.
Mon Jan 6 14:20:02 1992 Phil Nelson (phil at cs.wwu.edu)
* (number.c) Changed the out_num routine to use a correct field
size for bases greater than 16. e.g. For base 1000, each
"digit" is a three digit number.
* (Makefile) Added the "8" flag to get an 8 bit scanner.
* (scan.l) Changed "char *" to "unsigned char *" to match the
declaration of yytext for the 8 bit scanner. Also added code
to detect the null character in strings and generate an error.
Sat Jan 4 20:32:20 1992 Phil Nelson (phil at cs.wwu.edu)
* (const.h) Changed BC_BASE_MAX to INT_MAX to allow more bases!

Added the $(CC) the configure call. Moved some defines
toward the front of the Makefile to make sure they are
read by installers. Also added SUBDIRS variable and updated
the GNU distribution to include the subdirectories. Included
math.h in the distribution for use by configure. Included
ChangeLog in the distribution.
* Split the README into README and Install. Changed Install
to have current information. Documented the STRINGS_H define.
Updated the version number in README.
* Added a check for <strings.h> in configure.
Fri Nov 22 15:06:32 1991 Phil Nelson (phil at cs.wwu.edu)
* Changed configure to check for varargs.h first. Also, added
checks to see if long strings (math.h) are accepted by the
C compiler. Also added parameters to configure.
* Deleted #include <sys/types.h> from proto.h. Also made only
ANSI C compilers include <stdlib.h>.
