two thoughts spring to mind:

1. unless they're huge, it's often better to just rewrite crufty old
cgi scripts from scratch.  at least that way you'll know that they've been
written with best practice (incl. best security practice) in mind.

actually, even if they're huge it's still a good idea. it just takes
longer :)

2. if the config files are just perl (or very perl-like) code, have you 
considered replacing the "while(<IN>)" loop with just "require A.cfg;" ?

that would require editing the .cfg files to add "my" in front of variable
assignments, so that it works with strict...but may be the simplest fix.

alternatively, as you suggest, pre-declare them in the main scripts.
