Tom,

Thanks for the reply. I've implemented your suggestion and the warning goes
away. perlAPI.c is our own source file of functions which allows access to
the Perl interpreter which is linked in with the application. We use this to
access various Perl hashes that configure and control the system. We'll do
some serious testing to see if I've broken anything.

As usual, thanks for your invaluable assistance...
