Thanks. "const void" is a type that's different from "void"... I 
wouldn't get there by myself :-)

Also, I'm trying to compile valgrind using clang. valgrind doesn't use 
any libc functions (due to possible false warnings) so it uses GCC's 
__builtin_{set,long}jmp(...). I noticed they're not implemented in clang 
(and may never be... even in GCC's docs I didn't find anything about 
those builtins (only that the ADA backend uses them).

How could I get this to work? Is there any other way short of building 
(with GCC) a *.o file that exports those definitions or implementing it 
myself?
