Mon Jun  1 11:02:04 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* gsl_errno.h: added GSL_EUNSUP for errors caused by a hardware

	feature which is not supported on a particular platform

 	vector multiplication)

Wed May 27 18:15:34 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* test.c (gsl_test_str): changed things so that the strings aren't

 	printed unless the string equality test fails (usually they were

 	too long)

Mon May 18 17:58:20 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* test.c (gsl_test_rel): added a test for numerical quantities,

 	given a result, an expected result and an allowable relative

 	exceeded.

Sun Apr 19 19:14:05 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* strerror.c (gsl_strerror): added an strerror function for making

 	readable descriptions of the error number

Wed Apr 15 21:59:57 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* added a stream handler, for the error stream

	* completely reorganized the files, but the functions are

 	relatively unchanged

Wed Apr  8 13:55:48 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* gsl_errno.h (GSL_ERROR_RETURN_NOTHING): added an error macro

 	suitable for void functions

Mon Apr  6 14:10:48 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* gsl_errno.h: use enum instead of #define for symbolic constants,

 	so that they can be seen in the debugger

Sun Apr  5 19:49:17 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* err/errno.c (gsl_error): now takes gsl_errno as an argument

 	(this is useful for doing conditional breakpoints)
