+       gettimeofday: fix C++ crosscompilation
+
+       Never replace gmtime and localtime by macros when compiling with
+       C++, this prevents <ctime> from being included.
+
+       * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Do not
+       define gmtime and localtime as preprocessor macros.  Instead
+       define some HAVE_GMTIME, HAVE_LOCALTIME, REPLACE_GMTIME, and
+       REPLACE_LOCALTIME substitutions.
+       * lib/time.in.h: Declare gmtime and localtime when needed.
+       * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): AC_SUBST HAVE_GMTIME,
+       HAVE_LOCALTIME, REPLACE_GMTIME, and REPLACE_LOCALTIME.
+       * modules/time: Depend on gettimeofday, and substitute the above
+       variables in time.h.
