Re: perl - finding files that don't exist?

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.

Cygwin has always recognized these devices because the underlying Windows
APIs do.  Try "ls PRN" anywhere.
