The solution is to break your habit of saying "perl foo.pl".

If the first line of a text file begins with "#!" and a valid path name 
to an executable follows it, Cygwin -- like any *ix -- will consider the 
executable to be the interpreter for that file, and pass the script as 
the first argument to the interpreter.  So, if you put:

	#!/usr/bin/perl

at the top and run it with the command "foo.pl" from a Cygwin Bash 
prompt, you get Cygwin perl.  No need to reference perl explicitly.

If you find that you still need ActiveState Perl, you can use Windows 
Explorer to associate .pl with it.  Then if you run foo.pl from a Run 
box, an Explorer window, or a cmd.exe prompt, you get AS Perl.

None of this helps if you want to use AS Perl from Cygwin or vice versa, 
of course.
