+Subject: [PATCH] configure: allow libpostproc without gpl flag
+
+There may be GPL'ed programs in a distribution which want libpostproc,
+while other GPL-incompatible programs use some of the other libraries
+provided by ffmpeg.
+
+Since we know the license of libpostproc, we mark the resulting binary
+package accordingly instead of refusing to build it.
