	double-precision even on extended precision architectures

2000-05-14  Steve Robbins  <[e-mail]>

	* acconfig.h: 
	* configure.in: look in both <float.h> and /usr/include/float.h,

	symbols into the `fixed' header.

Thu May 11 12:47:19 2000  Brian Gough  <[e-mail]>

	* gsl_math.h (GSL_POSZERO): added macros for IEEE signed zeros, +0

 	that will be possible to work around compilers that don't
 	understand the difference between the constants -0 and +0.

Wed May 10 11:30:15 2000  Brian Gough  <[e-mail]>

	* gsl_math.h (GSL_POSINF): make use of HUGE_VAL which is actually

 	defined (it is only defined on IEEE machines)
	(GSL_NEGINF): as for GSL_POSINF

Fri May  5 11:20:50 2000  Brian Gough  <[e-mail]>
