+Subject: [PATCH] Use substituted GDCFLAGS
+
+Use the substituted value for GCDFLAGS instead of hardcoding $(CFLAGS) so
+that the subdir configure scripts use the configured value.
+
+	* configure.ac (GDCFLAGS): Set default from ${CFLAGS}.
+	* configure: Regenerate.
+	* Makefile.in (GDCFLAGS): Substitute @GDCFLAGS@.
