* time/strftime.c: Use canonical autoconf nugget for time.h+sys/time.h
include.
Mon Apr 29 02:48:26 1996 Ulrich Drepper <drepper@cygnus.com>
* ctype/ctype-info.c: (__ctype_width): New variable.

* locale/C-collate.c, locale/C-ctype.c,
locale/C-messages.c, locale/C-monetary.c,
locale/C-numeric.c, locale/C-time.c: Change copyright.
* locale/C-ctype.c (_nl_C_LC_CTYPE_class32): Correct
endianess for initialization value.
* locale/lc-ctype.c (current): Add parameter for offset.
(__ctype32_b, __ctype_width): Add initialization for these
variables.

width table are known to name table.
(ctype_output): Correct handling of class and map name
information and write out width information.
(find_idx): Prepare for being called with NULL pointer as
TABLE argument. This means only allocate name entry.
