Summary: distutils don't respect standard env variables

Initial Comment:
Using environment variables INCLUDE and LIB is a
standard way to set system-wide paths for C compilers.
However distutils.msvccompiler always overwrites these
variables with it's own values, which means users have
no way to customize their MSVC setups. It should
*append* the Python-specific stuff to the variables,
not overwrite them.

This bug was fixed in Python 2.5. If the environment
variables MSSdk and DISTUTILS_USE_SDK are set, then
distutils doesn't attempt to overwrite LIB or INCLUDE.
