That's a gdb error. Normally, I would advise you to try the gdb mailing 
list for better advice, but I suspect you may be attempting to build 
something quite old...

For Insight, definitely grab CVS HEAD or git. If you *really* want a 
release, try grabbing the latest gdb release and copying the gdb/gdbtk 
and libgui folders inside it. But I suspect it will be much easier for 
you to just grab the latest sources. FWIW, I use this daily for my own work.

Or you could pass "--disable-werror" to configure to suppress erroring 
on warnings.

If you need to get your specific error fixed, try emailing the gdb@ 
mailing list.
