+ strftime: remove dependencies on multibyte modules
+
+ strftime depended on mbrlen, mbsinit, and wchar, but these modules
+ are needed only if ! MULTIBYTE_IS_FORMAT_SAFE, and that is true
+ only if __osf__ is defined, and I suspect OSF doesn't need these
+ other modules. If my guess is wrong, we'll need to come up with a
+ variant of strftime that doesn't need the multibyte modules.
+
+ I discovered this problem when attempting modify Emacs to use the
+ strftime module. With the previous gnulib, this caused Emacs to
+ need 31 new files, ranging from lib/config.charset to
+ m4/wint_t.m4. This was overkill and I expect would be offputting
+ to the Emacs maintainers. After this change, only 6 new files are
+ needed, namely strftime.[ch], srtftime.m4, stdbool.in.h,
+ stdbool.m4, and tm_gmtoff.m4.
+
+ * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always.
