	* posix/glob/configure.bat: Fixes from DJ.

	* time/backward, time/europe, time/northamerica, time/pacificnew,
	time/zdump.c, time/zic.c, time/tzfile.h, time/private.h,
	time/ialloc.c: Code and data updated from ADO's 95b.
	* time/emkdir.c: File removed.
	* time/Makefile (distribute, extra-objs, zic): Omit it.
	
	* time/localtime.c: Deansideclized.  Never #define __tzname et al
 	to non-__ names.

	* locale/lc-ctype.c (__ctype_tolower, __ctype_toupper): Use int *
 	instead of short int *.
	* ctype/ctype-info.c: Likewise.
	* ctype/ctype.h: Likewise.

	* locale/langinfo.h (_NL_CTYPE_CLASS): Use this (just one) instead
 	of EB and EL versions.
