Re: Patch for missing sinf, cosf, ... [was: wchar_t working on sparc-sun-solaris2.6]

[Branko Čibej <branko dot cibej at hermes dot si>]

Sigh ...

I really should check things more carefully. Please ignore my
previous patch; this one should be better.

2000-06-05  Branko Cibej  <branko.cibej@hermes.si>

	* acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Check for sinf,
	cosf, fabsf and sqrtf with AC_REPLACE_MATHFUNCS.

	* math/Makefile.am (EXTRA_DIST): Add sinf.c, cosf.c, fabsf.c, sqrtf.c.
	* math/sinf.c, math/cosf.c, math/fabsf.c, math/sqrtf.c:  New files.
