Just tested and it seems to work fine apart from one problem. When LANG 
is set to default C.UTF-8 I get random fork errors. I found a workaround 
because I don't like to use Cygwin in Finnish so setting LANG=C fixes 
the problem. I've attached a log that shows the errors. Otherwise Cygwin 
works fine with your latest patch, I managed to compile Cygwin itself 
without any problems.
