[FFmpeg-devel] CONFIG_W64_DEMUXER and dead-code elimination

I've noticed that when CONFIG_W64_DEMUXER is defined to zero that ffmpeg compiles in a reference to ff_w64_guid_data but doesn't not link w64.o (which defines that symbol). This normally works because most optimizers discard the reference to ff_w64_guid_data early enough to not cause a linker
