This sounds reasonable to me. AFAIUI from irc backlog, win64 support has
never really worked. Just to be sure, did ffmpeg 0.5 work on win64? If
not, this isn't a regression.

In any case, I think that disabling with a proper error message seems
most reasonable for me in th 0.6 series. Can you please implement this
changes in the 0.6 branch? Thanks!

In case this is a regression, we can consider reenabling win64 support
in a later in a later point release.
