annoying warnings with use of Texi2HTML::Config namespace

Hi,

I have implemented the ideas about namespace separation, and I am happy with
the result, except that I get 52 lines like that when running with -w:

Name "Texi2HTML::Config::DEF_TABLE" used only once: possible typo at ../../texi2html.pl line 902.

Of course it is not a typo, it is just that the $DEF_TABLE variable is 
defined and initialized in the Texi2HTML::Config:: namespace, and is used 
only once in the main:: namespace. Any idea how to avoid these warnings ?
