Compilation
The latest GHC chokes on the latest HaskellDirect file src/Utils.lhs.
Here is a copy of error message and attached is the src/Utils.lhs file.
It will be seen from the file that ghc is objecting to an explicit
universal quantification. What should I do?

Untested, but changing the occurrence of '-syslib exts'
to '-fglasgow-exts' in the first setting of
SRC_HC_OPTS in src/Makefile may just take you past this
one..

In that case I get another error message:
The struggle continues . . .
after the hacks suggested by Sigborn and myself, Utils went through,
as did a lot of other HaskellDirect files, but now I get the following
messages. So we have a bug in GHC itself, with a non-exhaustive match
in ghc/compiler/typecheck/TcMatches.lhs. The version of

Int arithmetic on GHC and Hugs is modulo 2^32, i.e. maxBound + 1.
Actually, if we are in nit-picking mode, arithmetic is modulo (maxBound+1)*2.
PS. I.e., if we interpret "modulo" in the right way since the result is interpreted
as a signed
