+Subject: [PATCH] libmp3lame: don't check unused function in detection
+
+hip_decode_init() isn't used by the wrapper, and can be absent from the
+library if lame was configured with --disable-decoder (like it is done
+for windows builds of VLC)
+
+Unfortunately this also removes the way to detect a libmp3lame more recent
+than the buggy 3.98.2
