| O.K., here's the first patch. It fixes problems with missing c9x math
| functions on sparc-sun-solaris2.6.
| 
| Although the builtin functions exist, it seems that GCC sometimes
| can't expand them inline and generates a call to the library function
| instead. Thus, libstdc++ on Solaris contains references to sinf, cosf
| and sqrtf. This patch provides implementations of these functions
| (and fabsf which is also built-in, although it's not causing a problem
| for now). This solution is generic and should work on other systems
| that don't provide these functions.

| 
| 	* acinclude.m4 (GLIBCPP_CHECK_BUILTIN_MATH_SUPP): Check for sinf,
| 	cosf, fabsf and sqrtf.
| 
| 	* 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.

Brane,

Thanks you for your patch.  I'll look at it closely.
