On the other hand, it can be annoying.

I can't use Python 2.4 right now because NumPy won't run.  So, I need to
wait for NumPy to get updated.

Of course, one would say: but NumPy is open source, go build it yourself.

My answer is simple: If there are more then 24 hours to a day, I definitely

Short answer to Jive's question: (1) free non-MS C compiler (either
MinGW or Borland) (2) inner calm.

I really can't understand what all the screaming and yelling is about.
Windows Python is built using an MS compiler. Those extension
developers who can't/won't buy the MS compiler use either the free
MinGW compiler or the free Borland 5.5 compiler (or both!). Yes, you
have to be careful about mixing the runtimes. An extension that tries
to use a FILE * that was created by Python will crash. Using free() on
a pointer that was malloc()ed by the other party isn't a bright idea
either. There are adequate solutions to these problems, involving
Python-supplied higher-level functions instead of C runtime functions.
Otherwise, not a problem. Distutils has made the process of using MinGW
and bcpp a snap. The documentation is adequate. When a new version of
Python comes out, one rebuilds and tests one's extensions. So ... now
there are THREE compilers that can be used instead of the one that
Python's built with; what's the big deal?
