perl -x doesn't recognize file as executable

You mean special logic for windows file permissions (ACL?), not only
using the owner/group/other scheme?

>>$ perl -e 'if ( ! -x "/cygdrive/c/Programme/NSIS/NSIS.exe" ) {print "not

I beg to differ ;) Technically it depends how you define executable, if
you only know ugo permissions (or whatever this scheme is called)
then it it *not* executable.

If you decide to just test it and try to execute it you will see
that it executes quite well.

So IMHO it is executable, but technically some programs might not
see that because they are looking at the wrong place.

$ getfacl /cygdrive/c/Programme/NSIS/NSIS.exe
# file: /cygdrive/c/Programme/NSIS/NSIS.exe
# owner: Administratoren
# group: none
user::rwx
group::---
group:SYSTEM:rwx
group:Benutzer:r-x
                  ^
with ------------|

So it is executable. But ugo rights do not show this

I know that I can work around this, but Joe Average might not have
the rights to change the ownership of a file because he might not be in
the Admin group.
