Changes from 1.16:
# New: Several more packages of hierarchical libraries are included in
the build: base, parsec, haskell-src, QuickCheck, HaXml, HUnit, Cabal.
# New: FFI improvements: foreign import "dynamic" is now supported, and
named C header-files are now used.
# New: The compiler now uses cpphs for Haskell source instead of cpp. This
removes problems with string gaps, primes in identifiers, and so on.
# New: In hmake-interactive, if the readline library is not available,
the simple line editor now has a history mechanism.
# Bugfix: hmake's processing of cpp conditional directives is improved also.
# Bugfix: More evil bugfixes for gcc versions ? 3.3
# Bugfix: A numeric pattern can now match against a Num newtype.
# Bugfix: Foreign imports and abstract newtypes now play OK together.
# Bugfix: Methods in qualified classes no longer need to be qualified in
instance decls.
# Bugfix: GreenCard now accepts <<.../...>> syntax.
Changes since 1.14a include:
* A large subset of the base package of hierarchical libraries is now
included in the build.
* The primitive FFI mechanism has been updated to match the latest official
spec, and the full Foreign libraries are also included (in hierarchical
form).
* The library function List.sortBy now uses a stable O(n log n) mergesort.
* Numerous other small fixes, including revisions to the Haskell'98 standard.
Changes since version 1.06 include:
* Lots of bugfixes.
* The Hat tracing system is now entirely separate from the nhc98 compiler
(and is thus not included in the package)
