Clang is not able to eliminate the reference to ff_spdif_probe() when
there is a goto target in the same block and optimization is disabled.
This fixes the following build failure on OS X:
./configure --disable-everything --disable-doc \
--enable-decoder=pcm_s16le --enable-demuxer=wav \
--enable-protocol=file --disable-optimizations --cc=clang
make
...
Undefined symbols for architecture x86_64:
"_ff_spdif_probe", referenced from:
_set_spdif in libavformat.a(wavdec.o)
ld: symbol(s) not found for architecture x86_64
