[C++-sig] compilation problems with mingw v2.0

[eric jones]

We've handled this in SciPy by automating the process in
scipy_distutils.  The file scipy/scipy_distutils/mingw32support.py and
lib2def.py are used in the process.  Here is a (long) link to
mingw32support.py in our CVS.

/viewcvsx.cgi/scipy/scipy_distutils/mingw32_support.py%3Frev%3D1.7%26con
tent-type%3Dtext/vnd.viewcvs-markup

lib2def.py may not be as general as the solution mentioned on the web
page, but it works fine for all the Python's we've tested against.  We
did modify it some to make it work for any version of Python.  And,
since it is all pure Python and doesn't require any externally installed
binaries, perhaps something like it can be worked into the boost build
process.

On a related topic, I'm getting seg-faults when using weave with
Mingw2.0 (gcc 3.2) when running with the standard MSVC 6.0 compiled
Python.  Switch weave to using gcc 2.95.3 or MSVC 6.0 and all the
problems go away.

I haven't had a chance to investigate any further than knowing it is a
problem.  It sounds like boost is working fine which is a relief.  I was
worried that there was some irreconcilable MSVC-C vs. gcc3.2-C++ ABI
issue.
