Warnings clarification

Hi, I've been using Perl for several years to develop simple CGI applications 
for my 
clients. I'm now in the process of migrating to mod_perl for the performance 
benefit 
it gives. In so doing, I've been lurking on this list and reading the Guide.

Presently, I'm trying to debug a problem with a segmentation fault in the Petal 
module that Jean-Michel Hiver announced a couple weeks ago on this list. As I 
was 
reading the guide, "The Importance of Warnings" section in the Debugging 
chapter, 
suggested setting PerlWarn On on the development machine. My question is 
whether this setting is the same as the -w switch and the 'use warning' 
pragmas. I 
suspect it is, but the guide did not clarify this point.

Thanks,
William
