We know about it, but I don't think we have the right answer. I was
hoping the right answer is to include <pyconfig.h> before any system
header on all platforms, but we found out the hard way that this leads
to problems with VC and Codewarrior under Windows. We still need to look
at this issue very carefully and do a lot of testing on all platforms
with all combinations of debug, debug-python and release builds.

At the moment I am thinking a start would be to rework
boost/python/detail/wrap_python.hpp and include it everywhere we
currently have the Tru64-only <pyconfig.h> includes in the 1.30.0
release.
