I agree.  IMO, we could take the following approach:
* Look in C:\Program Files\The default place\...
* Look in \Program Files\The default place\...
* Try and import win32api, catching the import error

And if that fails, give the user a nice polite message.  This is likely to
catch 95% of the cases, and still make it obvious what the user should do in
the small percentage left...

However, it is worth noting that running "vcvars32.bat" wont work if run via
a seperate "system()" call - the environment variables set will not persist.
The only decent solution I can see is to create a temporary batch file, that
first calls "vcvars32.bat" before the builds.  Depending on how distutils
does its thing, it may just be simpler to detect the condition, and politely
ask the user to run the batch file themselves...
