Yep, looks like I missed some.
get_current_dir_name, setresuid and setresgid (as well as forkall...)
are the only ones that aren't defined with _BSD_SOURCE.

Still, I tend to prefer having some respect for even unofficial
namespaces.

Attached is a patch (3rd revision) that has all the _BSD_SOURCE
functions properly classified.
