glibc/sysdeps/mips/bits/fenv.h
Ulrich Drepper 417bafec1e Update.
* stdlib/Makefile (headers): Add bits/wchar.h.
	* sysdeps/unix/sysv/linux/i386/bits/wchar.h: New file.
	* sysdeps/generic/bits/wchar.h: New file.
	* sysdeps/generic/stdint.h: Include <bits/wchar.h>.  Use values in this
	file to define WCHAR_MIN and WCHAR_MAX.
	Change UINT*8_MAX and UIN*16_MAX value to type int.
	* wcsmbs/wchar.h: Include <bits/wchar.h>.  Use values in this
	file to define WCHAR_MIN and WCHAR_MAX.
	* sysdeps/alpha/fpu/bits/mathdef.h: Make FP_ILOGB0 and FP_ILOGBNAN
	int values.
	* sysdeps/arm/fpu/bits/mathdef.h: Likewise.
	* sysdeps/generic/bits/mathdef.h: Likewise.

	* locale/locale.h (struct lconv): Add __ prefix to the new members
	if not C99.
	* sysdeps/generic/inttypes.h: Remove unnecessary imaxabs and
	imaxdiv optimizations.
	* sysdeps/wordsize-32/lldiv.c: Add hack to make alias work.
