Does anyone have any hints in configuring Python for BeOS?

The Problem:

I've managed to compile it but under make test it just hangs on 
test_p_open2.py. Once I remove that file from the testing sequence seems 
to go into an infinite loop after test_threading. Also the struct module 
test failed as well.

A possible path to the solution:

Well, I have three hints:

 1. Change the optimization from '-O3 -mpentiumpro' to just plain '-O'.
    I'd start with a clean unpack of the distribution and make this
    change to "configure", and then run configure with the usual flags.
    (--with-thread  --prefix=/boot/home/config)

That's the most important.  The problem with struct is some incorrect 
code from gcc -O3.  (I assume you're on Intel hardware.)  I don't know 
exactly what it does, but it works fine if I insert a printf.  Who knows 
what else could suffer, maybe the test_threading problem is also 
compiler error.  The worst thing was when some experiments with popen2 
dropped the whole system into the kernel debugger.

 2. Don't bother with test_popen2.  I don't know what's wrong with it,
    but it's going to hang.

 3. Don't bother with test_select.  Likewise don't know what the actual
    problem is, but BeOS select has bugs, defects, weaknesses etc.
    One thing you might fix in selectmodule.c, if you need select(),
    is to use FD_SETSIZE for the 1st parameter to the C function,     
instead of the calculated maximum size.

With those three changes, I made it through the test suite with only the
usual failures.
