Better error message when trying to declare CCallable & CReturnable instance of abstract type

add instance of Show for Addr.

Add bibliography for this file.  We don't have make rules to use it yet.

remove GHC/Hugs extension document from the user guide.

* swapped ST and LazyST.

add ghc/docs/libraries to the documentation built for a GHC binary
distribution.

add notes about library document and ':::' bug.

  that begin with '::'.
* remove duplicate ':' case from is_sym.
* add '::' as a builtin identifier, mapped to ITdcolon.

add new files for ':::' test.

Add test for ':::' interface-file lexing bug.

use '----' instead of '***' so as not to get confuesd with error messages

remove unreferenced files

Add runST.

add typechecker bug which we currently don't have a fix for

update tests for 2.10

another attempt at getting 'make -k' to do the right thing.

bump version no. to 2.10.

point to 2-10-notes.lit.

build SGML documentation using the normal 'gmake dvi' etc.

add skeleton Makefile

note about SGML-Tools.

litify, add a couple of things.

update for GHC 2.10, and add SGML2INFO.

update for 2.10

update for 2.10.

remove a couple more GHC dependencies.

cleanups to the bindist stuff.

Remove some of the BIN_DIST hacks, allowing us to build a binary
distribution for either Happy or Ghc (or various other projects when
these are set up).

make this Makefile package-independant.

project-ify the bin-dist rules a bit.

Add SGML suffix rules.  Single-file documents only for the moment.

Move GHC ANNOUNCE message into GHC subdir.

add sgmlverb.

Add verbatim for SGML.

bump happy version number to 1.5.

release notes for 2.10.

Treat $(PROJECTVERSION) as a string, not a floating point number, to
avoid rounding errors.

Fool cpp into substituting for PROJECTVERSION within a string by using
string gaps, not forgetting the space after the '\' at the end of the
line to fool cpp into leaving the '\' behind :-)

import DsM, seems to be required for ghc-0.29.

Move a few instances of the Bounded class from PrelBase out into a new
module PrelBounded.

This enables the minBound value for Int to be fixed using a Literal
Literal (using litlits requires an import of CCall, which imports
PrelBase, hence the need to move this stuff outside).

Restore perl4 compatibility.
