 The following configurations fail:

 {{{
 ./configure --disable-everything --enable-demuxer=xbin
 ./configure --disable-everything --enable-demuxer=adf
 ./configure --disable-everything --enable-demuxer=idf
 }}}

 All giving the same error, save for the "In function" line which varies
 depending on which of those three demuxer is enabled:

 {{{
 CC      libavformat/bintext.o
 libavformat/bintext.c: In function 'xbin_read_header':
 libavformat/bintext.c:193:5: error: implicit declaration of function
 'init_stream' [-Werror=implicit-function-declaration]
 libavformat/bintext.c:193:20: warning: initialization makes pointer from
 integer without a cast [enabled by default]
 cc1.exe: some warnings being treated as errors
 }}}

 The problem is that the function init_stream() is inside an #if directive
 that needs the bintext demuxer enabled in order to be compiled.
 Said function should be outside that #if directive since it's needed by
 all four demuxers.

 For the record, i wanted to mention that i found this problem purely by
 chance thanks to the --enable-random feature added to git-master a few
 hours ago.
