+ 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.
