Using the following code, I cannot duplicate your problem. I am also running ActiveState 5.6.1 build 629. 

#!/usr/bin/perl -w
use strict;

use constant PROJECT => $ARGV[0];
use constant ARCHIVE => $ARGV[1];

print "PROJECT value = " . PROJECT. "\n";
print "ARCHIVE value = " . ARCHIVE. "\n\n";

if (ARCHIVE eq "")
{
   warn( "No archive file was supplied.\n");
   exit 1201;
}

print "Still running\n";

This consistantly gives the warning: No archive file was supplied. and then exits.

I tried to reproduce your example accurately. Is there something I left out of my code that might account for your strange behaviour?
