This patch implements the new 'class foo():pass' syntax
for the ast branch. It also includes minor modifications
required to run build graminit.c on windows machines.

Do you know why graminit.c stopped working on Windows?
Kurt's report on the merger didn't show any issues on
Windows and so I wonder if the problem goes back to the main
branch as well.

graminit.c is generated by pgen.exe. This process isn't fully
automated on a windows build (like I'm guessing it is on
linux). There is a provided makefile that works with visual
studio's nmake for windows users. It just referenced an older
version of the python lib file (2.3 instead of 2.5).

I presume this hasn't caused problems in the past becuase
people modifying grammar/grammar have been running some
form of *nix.

Now I'm starting to wonder if pgen generates any other files
(i.e. header files) that I didn't include in the patch. I'll verify
when I get home.

Just to confirm, pgen did generate a new graminit.h file, but
there were no changes to it because we didn't add any new
symbols. The patch I submitted is fine.

Looks good. Check into the AST branch. Thanks for the patch.
