Hi list,

I think we need a new GCC option added to configure.in:


This option came into existence with GCC 4.6 and is causing havoc all over.
I've been going through a lot of dissectors, many of which have either:
* unused set variables
* variables set for a legitimate purpose, but not used (yet)
* bugs

I've fixes for a number of the (non-generated) dissectors and will 
commit them today.

Is there a (reasionably easy) way to use this option only when compiling in the .../dissectors directory ?
(I think that I've previously addressed the "unused_but_set" warnings 
for many (all ?) of the other directories). (SVN 37600 & following...)
