Have you tried compiling with a high WARNS level? No errors are
thrown, since <bsd.hostprog.mk> doesn't do anything with WARNS.
In any case: the only time a warning would be emitted is if you
(rather inexplicably) turned on -Wmissing-noreturn - which isn't
enabled by any other -W flags.

As far as fixing the build so that __dead doesn't produce compiler
warnings - please follow up to my query on tech-misc, message-id
<20071226105053.GB23538@babymeat.com>, which addresses precisely
this sort of issue. (Alternately, patch the code in whatever
fashion is acceptable.)
