But parser.c already contains code related to several other codecs like
MPEG-4 and AAC, MP2, MP3, AC3.  The rest of the AC3 parsing code is
there.  Also, without even more #ifdefs, when you need just this one
function, you have to link all of ac3.o into libavcodec.

The first patch adds 4 #ifdef conditionals, the second just one and to a
file that already has quite a few.  My vote goes to this variant.
