Just for my two cents, does "move perl into base" mean that a Cygwin 
install would always install Cygwin's perl and would not allow perl to 
be skipped?  I'm asking because we use ActiveState perl; we've had 
problems trying to run some of our scripts using Cygwin's perl. Every 
time a Cygwin install tries to bring in Cygwin's perl, we either have to 
mark it to be skipped or let it install and then run setup again to 
de-install it.
