[BZ #281]

	* posix/regex.h: Define RE_TRANSLATE_TYPE as unsigned char *.
	* posix/regcomp.c: Remove unnecessary uses of
	unsigned RE_TRANSLATE_TYPE.
	* posix/regex_internal.h: Likewise.
	* posix/regex_internal.c: Likewise.
	* posix/regexexec.c: Likewise.
	Based on a patch by Stepan Kasal <kasal@ucw.cz>.
