[PATCH] Fix wrong declarations of builtin functions

Hi,

I thought in preparation of the new C++ warning about wrong
declarations of builtin functions it would be good to fix some of the
more obvious bugs in the testsuite first.


Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?


Thanks
Bernd.
