No, that's too much pessimization. On top of that, it expose other compiler
bugs. Just recompile the suspect binary and/or libraries with "-O0 -g" and
install them seperately, like so:
	% cd /usr/src/lib/bind/isc
	% make cleandir; make cleandir
	% make obj
	% make depend
	% make DEBUG_FLAGS="-O0 -g"
	% sudo make install

To find out which libraries a binary uses, do:
	% ldd /usr/bin/nslookup

For code in the base system, I typically try to find a work-around so that
we can compile with the default flags.
