Log Message:
mpd: make this build on NetBSD/powerpc 10.0_BETA.

Seldom have I seen a program so crusty, e.g. wanting to declare
standard library functions on its own(!)  There are still *lots*
of warnings produced during the build.

"make test" has lots of tests failing for NetBSD/macppc, but at
least quite a few succeed as well.  That's at least something...
