There's a problem with that which I encountered during x264
development: apparently on MinGW, .bss is not guaranteed to be 16-byte
aligned.  This caused crashes in x264 until we solved the problem by
padding the array which caused the crash with a single "1" at the end
to force gcc to place it outside of .bss.
