I have problems in compiling GreenCard 2.0 with GHC 2.10.
Everything works just fine until the module "StdDIS.hs" is to be compiled...
'make all' stops with the following message:
ghc-2.10 -fglasgow-exts -fno-prune-tydecls -c StdDIS.hs -o StdDIS.o

I do not believe that "StdDIS.hs" does contain any errors so perhaps someone knows
where to find the bug elsewhere.
Thank you
