Update of /cvsroot/python/python/dist/src/PC/bdist_wininst
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv28252
Modified Files:
install.c
Log Message:
Patch #892660 from Mark Hammond, for distutils bdist_wininst command.
install.c: support for a 'pre-install-script', run before anything has
been installed. Provides a 'message_box' module function for use by
either the pre-install or post-install scripts.
bdist_wininst.py: support for pre-install script. Typo (build->built),
fixes so that --target-version can still work, even when the
distribution has extension modules - in this case, we insist on
--skip-build, as we still can't actually build other versions.
