+Subject: [PATCH] Makefile.PL: fix cross-compilation with gdlib.pc
+
+Cross-compilation will fail if gdlib.pc does not contain any cflags.
+Indeed, if cflags is empty, Makefile.PL will use the default value for
+INC (i.e. -I/usr/include -I/usr/include/gd)
+
+It should be noted that gdlib-config has been dropped from gd since
+version 2.3.0
