Well, it tells you precisely what needs to happen -- <unistd.h> needs to
be included by the source file using vfork().

This warning does not happen on a -current system, but the toolchain has
not changed... and I don't see a reference to vfork in the libstdc++ sources,
however it is there in the object... hm.

So, I guess I'd say "fixed in current", but it'll take me a while to find
the actual problem source.
