Hi list,

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

AC_WIRESHARK_GCC_CFLAGS_CHECK(-Wno-unused-but-set-variable)
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
Two bugs are already addressed. I've got some code cleanup done, some stubs. 
Remains the generated dissector code which spawns many of these errors.
Therefore I think this item is needed.
I have lost the use of my development machine for at least another week, so 
can't work on this myself.

Thanks,
Jaap
