Hi there.
Well, I was sort of hoping that it would "maintain itself" in an open source manner, but if it needs an official maintainter, we can do that.  Particularly, we are interested in input from the community on how better to set up the projects in VS to perform the profile-guilded optimization step with minimal user input.  Our current approach relies on a file called pythoncore_pgo_link.txt which needs to be manually updated when the project changes significantly.

Martin, you have been doing work on getting python to be officially supported with VC 8.  I remember that we discussed this at the pycon sprint.  My VC8 build of 2.5 indeed did crash in the regression suite.  I have some ideas on how to fix the C runtime problem.  I will try some things locally and then bounce them off you and Tim.

Cheers,

Kristjan

p.s. do you think I ought to subscribe to python-checkins?

I'm copying Kristján directly since I doubt he's still following the python-checkins list actively enough to notice that replies "to him"
actually just go to python-checkins.

Kristján is actively using that directory in his business, so he's maintaining it for now.  At the NFS sprint he demonstrated significant speedups via exploiting profile-guided optimization, so it should of substantial interest over time.  If everyone loses interest, fine, then it becomes like PC/VC6/ and RISCOS/ and ... in the meantime, it doesn't get in the way of anything I ever do <0.5 wink>.
