User's Guide - release-2-10

Changes made since 2.09:

export some missing operations from `ST'/`LazyST'.
remove wired-in `runST' from the compiler, move `runST' from `STBase' to `UnsafeST' and give it a type signature. Fix a bug in the compiler to do with universal quantification so this actually works.
fix cut-n-paste-o in `PosixUtils.lhs'.
better code for checking for overlapping(incomplete?) patterns.
`-fwarn-simple-patterns' for pattern-bindings that could fail.
win32 green-card stubs imported.
fix 'make carries on after errors' problem again.
driver fixed to be perl4 compatible again.
obscure happy bug fixed.
`Word' removed from hbc library to avoid conflicts.
lots of fixes to the binary distribution system - you can now do `gmake binary-dist Project=Happy' from the top-level and get a Happy binary distribution. GHC binary distributions no longer contain Happy.
add some suffix rules for SGML, we can use SGML-Tools for documentation now.
added an new manual for Happy, in SGML format.
added the GHC/Hugs extension library documentation as a separate document, and removed that information from the Users' Guide.
Fixed a bug where ':::' wasn't being parsed properly in interface files.
Fixed a long-standing bug in the strictness analyser.
Fixed the cause of the `getWorkerIdAndCons' panic.
Moved the array tests from ghc/lib into the test framework. ghc/lib/tests now doesn't exist.
