You can't use gcc for the RGB program. The problem is that gcc returns
structures differently than cc. On the sun3 there is an option to
-fpcc-struct-return, but it is listed as a bug with gcc that the switch
is ignored for the sparc. DBM is a cc compiled library that uses
structure returns.

Just compile that with cc. In fact, I am not sure why you are trying to
use gcc for the X stuff on the sparc. From my experience the code on a
sparc using gcc and cc is almost identical.
