I'm not sure what exactly is the issue here, but I seem to remember that
diff-mode does rely on the labels inserted by -L in order to implement
applying and reversing of hunks.  It could be that this feature can
therefore not work correctly under Solaris 8.  The -L feature is only
needed if VC performs a local diff though.  So perhaps switching off
local diffs (by setting vc-cvs-stay-local to nil) might help.

I'll copy Stefan on this, perhaps he can say something.
