Oh. Fair enough. 

I've installed VC6, and I still can't build extensions. I don't think
distutils is looking hard enough; it can't see VC6 even though I've run
VCVARS32.BAT, the environment variables are all there, and I can run CL.EXE
with no problems. 

Digging a little...

For whatever reason, I don't have any registry keys named
r"Software\Microsoft\Devstudio\6.0\Build System". I do, on the other hand,
have a convenient MSVCDIR environment variable once I run VCVARS32.BAT. 

I've submitted patch 780821:
