This patch enables the building of Cygwin Python with a static core

which still supports shared extensions. It takes advantage the latest
Cygwin binutils (i.e., 20030901-1) which can export symbols from
executables:

Additionally, it finally lays to rest the following mailing list
subthread:

http://mail.python.org/pipermail/python-list/2002-May/102500.html

I tested the patch under Red Hat Linux 8.0 too
