On the contrary, we're seeing a lot more instability with msys. :-(

Erik has seen lots of random crashes, I haven't seen many (just about 
one or two) but I have also seen hangs.

So we've basically taken the informal decision of not pushing the msys 
track any further. What's in there will work properly some/most of the 
time. It might very well be good enough for "community support", but it 
won't do to use in our build farms.

That's the reason for the renewed efforts to get cygwin working. We 
concluded that there seems to be just a single issue left with cygwin: 
if it hangs, it hangs at the "ctsym bug", so it should be doable to  
figure out what goes wrong and work around it. Msys, on the other hand, 
seemed much more generally unstable.

But we need to get either of them working, or we can't build with 
acceptable stability on Windows. So it's really a high priority issue 
for us.
