It was decided in the early distutils development to prefer the registry
entries over env variables. Heck, most of my C/C++ developer collegues
*never* run *anything* from the command line, or even know about the
msvcvars.bat, vcvars32.bat, and vsvars32.bat batch files.
Given the amount of complaints we get here about this, maybe the
decision was wrong.

Can't you use the include_dirs and library_dirs arguments to the setup
