The waring is because is because the declarations are not matching. It
looks like you found a system with savectx :-), what is the signature?
Can you update Builtins.def?

If you are sure that savectx doesn't return twice, please check with
the gcc folks too. They have the equivalent code since 1992 at least:

http://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=66d433c7be147672fb1da1afd42a311d79cb0531


What does savectx do on your system?
