+       Fix compilation error on mingw when module 'time_r' is not used.
+       * lib/time.in.h (localtime_r, gmtime_r): Declare only if GNULIB_TIME_R
+       is 1.
+       * tests/test-time-c++.cc (localtime_r, gmtime_r): Likewise.
+       * modules/time_r (configure.ac): Invoke gl_TIME_MODULE_INDICATOR.
+       * modules/time (Makefile.am): Substitute GNULIB_TIME_R.
+       * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): Initialize GNULIB_TIME_R.

        Fix compilation error with Sun C.
        * lib/strtol.c: Use LLONG_MIN instead of GCC specific LONG_LONG_MIN.
        Use LLONG_MAX instead of GCC specific LONG_LONG_MAX. Use ULLONG_MAX

   dnl Otherwise, replace only if someone compiles with -DGNULIB_PORTCHECK;
   dnl this lets maintainers check for portability.
