DX on LinuxPPC (working, sort of!)

["Marcus H. Mendenhall" <marcus.h.mendenhall@vanderbilt.edu>]

I have sort of got a running copy of DX on my LinuxPPC R4 system on a
Powermac G3/300 running.  There are some bizarre user interface bugs
(buttons keep getting bigger everytime a panel updates), but the diffs
attached below are at least enough to make it compile and run.  For some
reason, I also have to manually start the server (dxexec -r &) and then
connect to port 1900 to get things working.  A major problem was that
libpthreads breaks some internal handling of the errno global variable,
so I disabled it in the configure.in script for linuxppc.

If anyone else out there is working on this, please let me know.
