[PATCH] Another huge_val.h fix

[Jakub Jelinek]

Hi!

Sadly it turns out that eventhough gcc 2.95 handles hex floating constants
just fine (with __extension__ for -pedantic), g++ 2.95 does not, so everyone
now gets a fatal error including math.h in a C++ program.
Fortunately g++ 2.96 does (ObjC did already in 2.95), so IMHO we have three
choices:
- simply prereq 2.96 like done with this patch
- use # if __GNUC_PREREQ(2,96) || (__GNUC_PREREQ(2,95) && !defined(__cplusplus))
- kill the hex floating consts bits from huge_val.h

	* sysdeps/arm/bits/huge_val.h: Prereq gcc 2.96+, not 2.95.
	* sysdeps/i386/bits/huge_val.h: Likewise.
	* sysdeps/ieee754/bits/huge_val.h: Likewise.
	* sysdeps/m68k/bits/huge_val.h: Likewise.
	* sysdeps/sparc/sparc32/bits/huge_val.h: Likewise.
	* sysdeps/sparc/sparc64/bits/huge_val.h: Likewise.
