small improvements from Ian Lynagh

Code that uses deriving (... Data ...)
will require an updated *compiler* to be in line with
these new boilerplate modules.

Overall changes:
- Revised datatype/constructor representations.
- Enhanced API for construction and observation.
- Added many Data instances for prelude-like types.

To make it compile with nhc98, #ifdef out the Typeable[12] instances.

Update the comments in here after changes in rev. 1.17.

instances for Ordering and tuples (up to 5)

Simplified kind-polymorphic boilerplate stuff.

Follow-up fix triggered by yesterday's major scrap your boilerplate commit.

Thanks to Sven Panne.
The module should be back to Haskell 98
or at least should not break hugs anymore.

Added finalizeForeignPtr function

Twin traversal is now based on accumulating maps.
Added polymorphic type extension for type constructors.

Proliferation of unsafeCoerce in Data.Typeable stopped. (There is now
just one cast0 which generalises on all previous forms: cast, castss,
castarr.) Started classes Typeable1/2 for unary/binary type constructors.
Added instances for lists, products, sums, functions, maybies.

New version of translate for mingw32, which correctly (allegedly)
reverses the command-line translation done by the standard C runtime
on Windows.

Hugs has hSetBinaryMode, hPutBuf, and hGetBuf now.

wibble (replace helper function with fromEnum)

Preserve group/other bits in setPermissions.

Closes: SF 899533 Directory.setPermissions bug

stat() needs to be wrapped too

Also need to wrap fstat().

Use C wrappers for lseek() and open().  On Linux, these functions are
macro'd to different versions when large file support is on, so to
make the libraries compilable with the NCG we need to use C wrappers
for these functions.

Remove unused argument from commitBuffer

Exclude "config.h" inclusion for nhc98 as well as Hugs.

adjust imports for portability

Another commit of boilerplate refactoring
related to twin traversal and type introspection.
Clean-up. After some reflection the list
processing module was not regarded suitable
for the library (see List.hs removed).

Added support for tracers

Refactored the approach to Twin Traversal.
Added some illustrative treatment of polymorphic lists.

make import Foreign.C.String GHC-only to unbreak Hugs build

array doc updates

uncatched -> uncaught

The UncatchedExceptionHandler is defined only for GHC

Added interface to set/get handler for uncatched exceptions.
The handler is invoked from the GHC.TopHandler.topHandler or
Control.Concurrent.childHandler when an exception is catched.

Comments

Documentation for floatToDigits

Explicit for-alls for Monad (so desugaring knows which order to give type args)

Document non-std behaviour of array

Put double quotes around the -#include flag, so that command-lines can
be cut-n-pasted.

moved the monad transformer libraries into a separate mtl package.

Fix definition of 'partition' to match the (non-)strictness mandated by
the Haskell'98 Libraries Report version.

Hugs only: use the configure-set variable INLINE_ONLY instead of
`extern inline' (which works for gcc but not C99 compilers).

plug a warning

Excluding 'unfoldTreeM' and 'unfoldForestM' is overkill for nhc98.
A simpler workaround for the type inference bug is just to omit one
type signature from the mutually recursive pair.

Plumb in Data.Queue for nhc98.
