x264 writes its version number to the bitstream headers, for example
	x264 - core 27 svn-239

if you modify it, the newly compiled x264 adds "M" to this, so there is:
	x264 - core 27 svn-239M

so the header is longer by one byte and you can't use "cmp" to compare
directly the outputs of the modified and original versions.

I learned this by the hard way ...
