And thanks for the very accurate file/line references into the Cygwin 
source. I first tried making a patch but lost track in spawn.cc.

Sounds like a good solution.

I will try that.

Maybe - but then that would be a problem in itself: I installed Cygwin 
on my Vista machine yesterday by clicking setup.exe on cygwin.com. That 
machine has never run Cygwin before, so my cygcheck must be the cygcheck 
of yesterday.

In any case: thanks for the help.

Cheers,
Klaus
