This patch is an attempt to allow the exe in a single
file distribution to be renamed. The strategy is to
use the exe name if the zipfile name is empty.
Within build_exe.py, if zipfile is None then set
relative_arcname='' on line 765. This is not part of
the patch file.
This patch is untested---the base py2exe distribution
does not work under my MinGW installation. Somebody
with a working build system please test this and let me
know if it works. Thanks!
