This works with vcvars32.bat too.

One more reason why it is a good thing - it will be much easier to 
decouple MSVC and PSDK modules and reuse PSDK module with other 
toolsets. Basically it will be possible to enable PSDK-based build by 
listing required <path>, <include> and <library-path> in the usage 
requirements.
