* 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.
