	* results.c: now displayed PASS lines only if GSL_TEST_VERBOSE=1,
	otherwise only display fail lines by default.

Thu Sep 12 22:56:31 2002  Brian Gough  <bjg@network-theory.co.uk>

	* results.c (gsl_test_rel): catch NaN
	(gsl_test_abs): catch NaN

Fri Sep 28 10:40:21 2001  Brian Gough  <bjg@network-theory.co.uk>

	* results.c: use the definition STDC_HEADERS instead of __STDC__
 	as recommended by the autoconf manual

	* results.c (gsl_test_factor): fixed factor to work for case of
 	0==0 without dividing by zero

Wed Nov 29 10:42:57 2000  Brian Gough  <bjg@network-theory.co.uk>

	* results.c (gsl_test_factor): added a test for two results being
 	within a given factor of each other (e.g. "result should be good
 	to within a factor of 2").  Note that this is different from the
 	definition of relative error, which starts with a measurement of
 	the difference by subtraction.

	* split out gsl_test code from err/ directory
