Re: terminal.app fails with "Unrecognized color masks" on x4vncserver with -depth 16 (Ubuntu 8.04)

[Fred Kiefer]

Just a few weeks ago I made a change to the art backend that should help 
with 16 bit graphics between machines with different endianess.  Could 
you please try to get GNUstep from SVN and compile it yourself to see if 
this change fixes the problem?

I only have i86 processors, so I am not able to test this myself. If the 
problem persists, could you please report back.
