Thanks Mark for catching it.

It puzzles me how it passed all other compilations (internals and
externals) without failures. On my machine (x86-64), old and new
versions compile without errors.

This failure isn't related to OUT assembly instruction, but to typo in
pointer name declaration. It was declared as "u32 *out", but "outb" was
used.
