regex: replace mbrtowc with __mbrtowc.

2009-01-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/regcomp.c (re_compile_fastmap_iter): Use __mbrtowc.
	* lib/regex_internal.c (build_wcs_buffer, build_wcs_upper_buffer,
	re_string_skip_chars, re_string_reconstruct): Likewise.
	* lib/regex_internal.h [!_LIBC] (__mbrtowc): New #define.
