Bob:

	All the lines are the same for me. Iwas on my 'real' computer
when I checked the sdl-config (I thought they would be the same.)

sdl-config --version is 1.2.15
sdl-config --libs is    -L/usr/lib/arm-linux-gnueabihf -lSDL
echo Linking mess...
gcc -Wl,--warn-common -s  obj/sdl/mess/version.o
obj/sdl/mess/mess/messdriv.o obj/sdl/mess/mess/coco.a
obj/sdl/mess/mess/mc10.a obj/sdl/mess/mess/dgn_beta.a
obj/sdl/mess/mess/shared.a obj/sdl/mess/libosd.a obj/sdl/mess/libemu.a
obj/sdl/mess/libcpu.a obj/sdl/mess/libsound.a obj/sdl/mess/libutil.a
obj/sdl/mess/libocore.a  -lexpat -lz -lm `sdl-config --libs`  -lX11
-lXinerama -L/usr/X11/lib -L/usr/X11R6/lib -L/usr/openwin/lib -o mess

	All look the same. I'm compiling it now on my Pi. Maybe a tool
update broke it.
