Hi Torsten

Thanks for that, I didn't know about this Cygwin tweak. I might try it
for my Perl issues, but the ActiveState version of Perl is now my
default and I will probably stay there.

Well, I'm no expert on cygwin - being most of the time on linux :-) -

The limit of 24 MB experienced by Allen seems a bit low, but maybe the
webpage helps nevertheless ...

Cheers,
Torsten
