Thanks for your help!

Before you answered I tried to rebase to a different base and then
wasn't able to use cygwin anymore, so I started with a clean install.
Until now it works, and when it doesn't anymore I'll try with making
the library writable first. I completely forgot about that. I always
seem to run into this problem when I try to compile rakudo. Any
thoughts on that? BTW: I am on xp.

best
Maurice
