============================

On PowerPC Macintosh, things are just weird.

* Using the stock compiler, you can't build gawk (c99 mode) against MPFR;
there is an issue with duplicate inline functions from GMP.  By default,
I have disabled this compilation.

* If you build GCC 4.2.4 and use that version of GCC, you can compile gawk
with MPFR and the C99 settings.  But then the two readfile tests fail.
The call to read(2) simply returns zero. I have no idea why.

Since nobody but me has one of these left, I'm not going to mess
with it anymore right now.

You may need to explicitly tell configure where to find the GNU gettext
header file and library with --with-libintl-prefix=...'. Otherwise,
the nlstringtest test will fail.

I have reports of success on this compiler:

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)

There are reports of compilation issues on Mac OS X 10.10 (Yosemite).
The only compiler reported to have produced a complete pass of
"make check" is the MacPorts compiler, /opt/local/bin/clang-mp-3.5.
