This patch needed a lot less defense than you posted -- the only
reason conditionals were implemented in that ugly way was Perl 4
compatibility.

I agree the new setup is much better.  For one thing it will
eventually let us fix the problems involving variables which are both
conditionally and unconditionally defined (including conditional use
of `+=').

Ok.
