[Pyrex] Testing on Linux

[Eric Wald]

I have hacked together some support for running the test suite on Linux
(and perhaps other Posix systems).  It may not be the best code, but it
runs on my system.  The patch follows this post.

Unfortunately, a few of the tests fail, and some others give warnings.
Is this normal, or an artifact of the different compiler environment?
I'm using Python 2.4.3 and GCC 3.4.3 (ssp).
