Summary: -flat_namespace not in Makefile.pre.in for Darwin/MacOS

Initial Comment:
Python 2.2a4 fixed Python 2.1's inadequate LDSHARED setting for Darwin/OS X as far as building Python is concerned.  However, it does not go quite far enough and the problem still exists for building other software that uses a similar configuration process, in particular Zope 2.4(.1).  It turns out that the top-level Makefile and Makefile.pre both have -flat_namespace correctly set, but Makefile.pre.in does not.  Since Makefile.pre.in gets installed in /usr/local/lib/python2.2/config, and other software using this build process reference Makefile.pre.in from there, -flat_namespace isn't set for the other software.  Manually adding:

LDSHARED= $(CC) $(LDFLAGS) -flat_namespace -undefined suppress

fixed the problem, at least for building Zope 2.4.  I don't know how much of that is actually needed other than -flat_namespace.

Please fix this for the real release!  The improvements for building on Mac OS X are wonderful -- it would be a shame for them to fail for the lack of one line in one file!

(I'm using Mac OS 10.1, in case that matters, with the developer tools installed.)

I'm not sure what you're suggesting we *do* here. We can't
add -flat_namespace to Makefile.pre.in, because it's a
platform-independent file. Also note that there's some name
confusion: the Makefile.pre.in that's installed in
.../config is not the same one that is used to build Python;
it's an old (and deprecated) way to build 3rd party
extensions, whose source is in Misc/Makefile.pre.in; the
current party line is to use distutils. Maybe Zope should
switch to using distutils too.
