git on 64bit windows - state of the art?

Hi,

I was wondering what the state of the art for running git on 64 bit Windows is?

I haven't tried it myself - my Windows VMs are 32bit - but colleagues are reporting persistent problems with the cygwin build because of (cygwin) rebasing issues [ the issue most often reveals itself as a failure to fork subprocesses while executing git svn ]

We have tried to use cygwin's rebaseall to address the issue per the advice on stackoverflow.com amongst other places, but this "solution" doesn't seem to produce permanent results (even if the installed cygwin code base remains stable). We tried msysgit to see if this provided any relief, but it had similar issues (perhaps because cygwin was also active at the time - I haven't had a chance to diagnose this particular more thoroughly yet).

Has anyone got a recipe that provides a permanent and stable solution to the (cygwin) 32/64bit rebasing issues?
