No, the one I just grabed off the Hugs webpage. I didn't even know HGL
was in the ghc/hslibs sources, I have to admit. Turns out the actual
sources are equal, but careful perusal of the Makefile in hslibs
revealed the vital clue: the -monly-3-reg option.
Compiling HGL with that makes ghc not choke on GreenCard's
ghc-targetted output (which it did before), and moreover makes it run
in full colour.
Excellent, thanks again for the help.
