X11, Release 5

Hi GRASS programmers,

Recently, we installed X11, Release 5 on our Sun Sparc Stations. Since
then GRASS does not display colors any more. Also grey scales seem to
be inverted. Apparently, the allocation of colors in Xwindow doesn't work
any more.

Recompilation of GRASS also didn't help.

Does anybody have an idea what the problem might be?

Thanks for your help.
