[gnu.gcc.bug] unimplemented __builtin_* functions

Can I ask that for the next version of gcc the builtins that aren't
implemented either draw an error message or get translated into
subroutine calls (or be omitted)?  I don't know of documentation that
lists the ones that are implemented, and some of them would be nice to
use.  The alloca builtin appears to work fine on the vax, and I've
just found that __builtin_memcpy is not implemented.  A list would be
really useful....
