Thank you for providing this document. Indeed, passing internal
pointers of one CRT lib to another is dangerous. But in most cases,
the python extension only focus on computational-intensive jobs
rather than API-intensive jobs. Therefore it is safe to let VS2003-built
python to call VS2005-built extensions with some attentions.

When you use distutil to trigger compilation, a special *python script*
will check whether the default compiler is VS2003. If there is no
VS2003, this script will pop-up the error for incompatible compilers.
I really really wonder how to *force* distutil to use my specified compile.
eg: (pseudo)
python build -c VC2005
python build --compiler=C:\VC8\cc --linker=C:\VC8\ld
