I am not sure where this issue should sits - is it a perl problem or a 
cygwin problem or windows?  Not sure - but I have noticed just after 
cygwin upgrade.

Perl seems to be finding files that don't exist:

$ ls -a
./  ../  Babel.pm

$ perl -e 'print (-f "./PRN.pm")'
1

$ perl -e 'print (-e "./PRN.pm")'
1

$ perl -e 'print (-e "./PR.pm")'


PRN.pm is reserved device in windows.  You can't create a file with this 
name in WinXP.  But perl says the file exists now and it did not seem to 
exhibit this behaviour before.
