This will be resolved in the next Perl release (5.8) where Perl uses its 
own IO (perlio).

Please use binmode for the files (scripts) and the mounts.

binmode() is not ignored on Cygwin.  Cygwin is not Win32!
Basically spoken: Perl on Cygwin works only correct if the files you are 
working with are in binmode and if you do it on binmode mounts.
E.g. pod2html fails on textmode pods, regardless which type the mounts are.

Huh?  I thought there are some problems using CVS with textmode files, but 
not with binmode?

Hmmm, there is this flag in perl.h, look for CYGWIN in perl.h, I tried to 
debug why it doesn't work as expected, but I didn't found the bug :(
