Why wouldn you want to tie yourself to a specific implementation of
malloc?  The _int_* functions have no interface which is in any way
universal and should be preserved if the implementation changes.

I've changed the code to use static since the generated code uses tail
calls.  This can perhaps be achieved with hidden as well but for the
above reasons I need more convincing.
