perl test fails

[Rob Clack <rnc at sanger dot ac dot uk>]

Not sure if this is the right list for my question.

cygwin 1.3.22-1 running under NT4.

I have a perl script that runs an executable, so before actually running 
it, the code checks that the file exists and is executable, but the test 
fails under cygwin.  Under linux and OSF1 it's fine.

I cut out the relevant fragments and built  a demo.  The idea is that if 
the "if ( -x script )" works correctly, then I should get "script is 
executable" as output.  Otherwise, it will execute the script, in which 
case the output will be what the script prints.

Hope someone can tell me why -x doesn't work the way I'm expecting.

Thanks
Rob

#!/usr/bin/perl
# this is the perl script, called "try"

if ( -x script)
{
	print "script is executable";
}
else
{
	system("./script");
}
-----------------------------------------------------------------------
# This is the 'executable'.  For the demo, it's just a script with +x
# permissions

echo "I damn well am!"
-----------------------------------------------------------------------
# Here is the output I get

rnc@ramsey ~
$ ./try
I damn well am!
