The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin. Specificially, these modules are:

_hotshot.c
_randommodule.c
_tkinter.c
arraymodule.c
bz2module.c
cPickle.c
socketmodule.c

Note that contrary to my recent email to
python-dev, I did *not* make the following
changes:

$ grep '\.tp_.*[ \t]*=' *.c
bz2module.c:    BZ2File_Type.tp_base = &PyFile_Type;
bz2module.c:    BZ2File_Type.tp_new = 
PyFile_Type.tp_new;
posixmodule.c:  StatResultType.tp_new = 
statresult_new;
threadmodule.c: Locktype.tp_doc = lock_doc;
xxsubtype.c:    spamdict_type.tp_base = &PyDict_Type;
xxsubtype.c:    spamlist_type.tp_base = &PyList_Type;

AFAICT, SF is still broken! I *did* check the upload
checkbox!

I'm probably missing some magic here: shouldn't there be a
patch to configure.in also to provide the necessary linker
options?

As for the SF breakage: you should file a bug for SF, in the
"alexandria" project. Perhaps better use a support request,
since that gets better attention.

Did you miss the following?

No, the defaults are sufficient.

Please (re)read the above URL. Let me know if
you need further clarification.

The bottom line is that the patch works correctly
under Cygwin. And, AFAICT, will not break any
other platform.

I had missed the fact that --enable-auto-import is enabled
by default. So the patch is fine, please apply it.
