U555 - solaris compilation bits

- If you have Gnome installed on solaris, the GETRES support wouldn't build.
I don't have access to a solaris system with Gnome installed, but hacked
unixconf.h to force the GETRES code itself to be compiled.  So, I believe the
unixres.c change will work for folks really using Gnome on Solaris.
Whether the rest of the gnome code will build there is beyond me.
- I accidentally left TIMED_DELAY defined and the Solaris build failed.
While solaris has usleep(), this is not part of SVR4 as far as I can tell.
But, SysV does have poll, so I implemented msleep() for SysV systems in
terms of poll.  So, you can now define TIMED_DELAY on any SYSV build.
