Original commit message from CVS:
* ext/faad/gstfaad.c: (gst_faad_setcaps), (gst_faad_chain):
Call functions with the correct API. Unfortunately, unless your
distribution patches upstream, the public header file for FAAD
doesn't actually declare the API accurately. So, some nastiness
ensues...

+/* These are the correct types for these functions, as defined in the source.

+ * these wrongly (in a way which was broken on 64 bit systems).
+ * Upstream CVS still has the bug, but has also renamed all the public symbols
+ * for Better Corporate Branding (or whatever), so we're screwed there.

+ * We must call them using these definitions. Most distributions now have the

+ * but not all, hence this Truly Evil Hack. This hack will need updating if
+ * upstream ever releases something with the new API.
