Solaris 2.0 and GRASS

Thu Aug 6 17:25:51 EDT 1992

I recently installed GRASS 4.0 on a Sun 4 Sparcstation running
Sun OS 4.1.  Now, that system is to be upgraded to the Solaris 2.0
operating system.  Can anyone tell me what if any consequences this
will have on my GRASS software?  In particular, will I need to
re-compile and/or change any scripts?  Will it work at all?  If
I need to recompile, will the makefiles that came with Grass
need to be modified?  How about the drivers?
