Yeah, that one's weird. IIRC the X11 protocol only allows for a
maximum of 32K width and height for an X11 screen, hence the use of
short. I'm not sure whether thats changed in future versions of X11 --
I tend to doubt it.

Those should be fine for the short term - the issue is if someone
does not want to build in the Xinerama support. It should probably be
wrapped like it's done in dtlogin/Imakefile:
#if CDE_USEXINERAMA
XINOPT = -DUSE_XINERAMA
XINLIB = -lDtXinerama -lXinerama
#endif
...
EXTRA_DEFINES = $(XINOPT)
LOGINXLIB = $(XLIB) $(XINLIB)
Feel free to make that change (or equivalent) and supply a patch. I
think most people would want Xinerama support, but it should be
goverend by the cf/site.def which is where it is typically
enabled/disabled for a build (#define CDE_USEXINERAMA ...).
