The one mentioned in the subject of my email. More specifically:
[Mon May 13 12:55:45 2002] Inst.cgi: Use of uninitialized value
in concatenation (.) at /u/web/cuesuo/cgi-local/admin1/Inst.cgi
line 22. 

This message appears when the shebang ends in -w and the
following two lines of code are in the program.
BEGIN{use CGI::Carp qw(carpout fatalsToBrowser);

I am not interested in suppressing the message; I'm interested in
removing its cause.
