Thanks for the patch,
I had to comment out some more stuff to get it working.. for anyone
interested following is the patch. This patch doesn't do much
otherthan making everything to compile as a 32-bit. This however only
solves the compilation part. 9vx crashes while launching acme,
resizing window etc (i.e nearly unusable). and this is true for the
9vx.OSX.gz binary in the mercurial repository.
