[PATCH] Add missing prototypes

[Eric Botcazou]

Hi,

This started with Steven's suggestion to check for the presence of ieeefp.h 
(where finite is declared on Solaris) and include it if present.  While I was 
at it, I added the prototypes for the functions in intrinsics/c99_functions.c
and discovered that fabsf was missing (but it's a compiler builtin).

Built and tested on sparc-sun-solaris2.8 and amd64-mandrake-linux-gnu.

	* configure.ac: Check for ieeefp.h.  Check for fabsf in libm.
	* configure: Regenerate.
	* config.h.in: Likewise.
	* c99_protos.h: New file.
	* libgfortran.h: Include c99_protos.h and conditionally ieeefp.h.
	* intrinsics/c99_functions.c (fabsf): New function.
