I made in this way, with string to change inside the 
binary, because if this string are not changed, starting 
with #, the binary will work like the normal perl.exe

Since this is made for HWXperl, when I delivery hwxperl I 
can get any binary of the release and turn into a script! I 
made this with miniperl.exe too, where you don't need the 
perllib in the same directory.

I don't understand what you means with 
"I don't think you need my @ARGS = @ARGV. Just work 
directly with @ARGV". Are you talking about the 'char argv' 
on the C code? If is about this, I just made in the most 
simple and portable way, because some compilers don't deal 
with argv equally.

about '$^O=~/(msw|win|dos)/', yes is not very pretty, but 
here, when the binary can't find it self, I will put all 
the options to fix this in any OS, here are only for Win32.
I saw one time a vendor with 'MSwin' in the $^O, but I 
think this is too old. Seeing again the table, I will 
change this line...

    OS            $^O        $Config{'archname'}

I will see your code on 'perl scripts executor on Win32'. 
Thanks for the link, and the reply...
