 # enough in this area it's likely we'll need to redefine

+# or  warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
+# the fix is

+#      but always AC_REQUIREd,
+#   2) to ensure that for each occurrence of

+#        AC_REQUIRE([gl_USE_SYSTEM_EXTENSIONS])
+#      the corresponding gnulib module description has 'extensions' among
