Re: ANN: pyMinGW support for Python 2.3.5 (final) is available

build host. The windows builds are done with a mingw cross compiler. It would be interesting if we could do this with python + extensions also. -- Nick Craig-Wood [EMAIL PROTECTED] -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list

Re: Python and version control

in Windows either. When I have to edit stuff on windows I use emacs. Cvs works fine on windows too. I haven't tried cvs in emacs on windows, but I suspect it will work fine as all emacs does is shell out to the cvs binaries. -- Nick Craig-Wood [EMAIL PROTECTED] -- http://www.craig-wood.com/nick
