Well, with Cygwin, you've at least got the ear of one of the Cygwin
maintainers, which should be worth something.
Even if I disappear, you can always send concerns to the Cygwin mailing
list. Do the ActiveState folks respond to complaints about things as
basic as pipes not working in perl?
Cygwin's goal is to make Windows look as much like Linux as we can
manage, so, unless we're total incompetents (which has been hinted in
this mailing list from time to time), it has *got* to be better,
source-code-wise to target Windows-running-Cygwin than
just-plain-Windows. However, as has been noted, that means that there
will be a speed tradeoff.
I think that, for most projects, the convenience of not having to
clutter the code with substantial accommodations for the windows/POSIX
mismatch usually offsets the annoyance of the speed penalty. Maybe
that's not the case for git, however.
Anyway, we're willing, within the limits of available time, to help out
where git uncovers issues with Cygwin. I just fixed some stuff in
dirent.h in the last Cygwin release, as a direct result of people noting
a problem here. Basically, I don't want git to be a morasse of #ifdef
__CYGWIN_'s and I'll do whatever I can to help.
We're always trying to tweak things to improve speed in Cygwin and am
open to intelligent suggestions about how we can make things better.
The dance between total linux compatibility and speed is one that we
struggle with all of the time and, sadly, over time, we've probably
sacrificed speed in the name of functionality. That's probably because
it's easy to fix a problem like "close-on-exec doesn't work for sockets"
and feel good that you've fixed a bug even if you've just added a few
microseconds to fork/exec.
