Added Read BufferMode instance

Bogus workaround to get cygwin32-b18 apps using Time compile and link

Added compatibility stubs for ST and PrimIO operators

Added comment on Read BufferMode instance

Make monadic operators (>>) and (>>=) left-assoc (as per Report.)

Added IOExts.unsafePtrEq :: a -> a -> Bool

New macros added to cope with new defn of ST

-monly-3-regs needed to have these compile with post gcc-2.7.2 snapshots under cygwin32-b18

Fix to have _casm_gc_ cope with statement blocks; misc import mods to have modules compile with 2.09 (and later.)

fix to have it compile with 2.09 (and later)

Removed superflous uses of hGetContents in main

fix to have it compile with 2.09 (and later)

New defn. of sstToIO and ioToRnMG to make them compile with new version of ST and IO

Misc changes to compile with new defns of ST, IO (and PrimIO)

Pull Maybe and Either out of PrelBase into separate modules in an attempt
to make PrelBase a little smaller.

define STArray using newtype, and defined unsafeInterleaveST properly
for the lazy ST monad.

merged into IOExts.lhs

GHC/Hugs Library document.

This currently won't build until we get the right SGML tools in the tree.

fix mistakes in last commit.

implement STArray using newtype instead of type.

add IOArray and relevant operations.

comment wibble

Add reallyUnsafePtrEq.

add two new primitive operations:

	quotWord#
	remWord#

for unsigned divides.

add compatibility cruft for PrimIO.

* simplify abs - it is just 'id' for naturals.
* use a special show for unsigned numbers.
* use special quotWord# and remWord# primitives.
* fix bugs in complement and shift operations.

* fix minBound::Int32 in view of the fact that minBound::Int is wrong.
* fix shift direction (it was reversed)
* fix complement to be a 1's complement instead of 2's complement

change minBound back until I can fix the bootstrapping problems.
Grrrr.
