nhc98

This release is mainly for maintenance, fixing
bugs caused by various versions of build compilers
(e.g. gcc-3.3), and adding support for many of the
new hierarchical libraries that are also supplied
with ghc-6.4 and Hugs, namely base, parsec,
haskell-src, QuickCheck, HaXml, HUnit, and Cabal.
FFI foreign import "dynamic" is now supported, and
C header-files named in an import are now
respected. nhc98 now uses cpphs rather than your C
compiler for preprocessing, which solves problems
with string gaps, primes in identifiers, and so
on.
