No need to apologize.  Also no need to have an understanding of the
environment; with a few rare exceptions it behaves just like a
Unix/Linux one.

The reason why I need to specify --allow-shlib-undefined is for the
python library; it's throwing undefined references to sincos even
though the symbol is there. Specifying that option is the only fix
I've found.

As mentioned earlier, i'm not familiar with python or its build
system; which file in the distutils dir do I need to modify?
