As I expected. I think this is fixed now (make fate passed all
mpegvideoenc tests, it's still running and I gotta run).

As much as I love and adore the new fate, I would've picked up this
crash earlier if Win64 (or win64/fate) wasn't such a pain to get
useful info out of. For one, "make V=1 fate" does not print out all
commands run on Win64 the way it does on Unixy systems. Also, the
error I got (which made me think I just broke Win64 in general) was
something like:

/home/rsbultje/ffmpeg/svn/tests/data/regression/vsynth1/error: line
134: tests/data/vsynth1.err: No such file or directory

What it should say is something like:

fate failed on vsynth1-error: Segmentation fault (or bus error, or whatever)

Can this be improved?
