   # If autoconf reports a warning
   #     warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
   # or  warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
   # the fix is
   #   1) to ensure that AC_USE_SYSTEM_EXTENSIONS is never directly invoked
   #      but always AC_REQUIREd,
   #   2) to ensure that for each occurrence of
   #        AC_REQUIRE([AC_USE_SYSTEM_EXTENSIONS])
   #      or
   #        AC_REQUIRE([gl_USE_SYSTEM_EXTENSIONS])
   #      the corresponding gnulib module description has 'extensions' among
   #      its dependencies. This will ensure that the gl_USE_SYSTEM_EXTENSIONS
   #      invocation occurs in gl_EARLY, not in gl_INIT.
