Yes and no. Yes, it is better to use the same compiler - but we
already break this rule with numpy, since numpy and python do not use
the same compiler. The problem with MS compilers is that you need to
use a different compiler for every python version; in particular,
there is no free version of VS 2003.net (the one used for python 2.4
and 2.5), and using VS 2005 or later will definitely not work.
Actually, the problem is not so much the compiler as the same C runtime.

No - but build against numpy 1.3, to avoid getting special
optimization flags which may render your binary useless for low-spec
