* posix/regex_internal.c (re_string_skip_chars): If no character has

	been converted at all, set *last_wc to WEOF.  If mbrtowc failed, set wc
	to the byte which couldn't be converted.
	(re_string_reconstruct): Don't clear valid_raw_len before calling
	re_string_skip_chars.  If wc is WEOF after re_string_skip_chars, set
	tip_context using re_string_context_at.
	* posix/Makefile: Add rules to build and run bug-regex25 test.
	* posix/bug-regex25.c: New test.
