	     The Glasgow Haskell Compiler -- version 4.08.2
	    ================================================

We are pleased to announce a new release of the Glasgow Haskell
Compiler (GHC), version 4.08 patchlevel 2.  The source distribution is
freely available via the World-Wide Web and through anon. FTP; details
below.

Haskell is "the" standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.
Haskell related information is available from the Haskell home page at

	http://www.haskell.org/

GHC's Web page lives at

+ What's new
=============

This should be a stable release.  There have been many enhancements
since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton
(US)).

There are the following changes

   - New profiling subsystem, based on cost-centre stacks.

   - Working x86 native code generator: now it works properly, runs
     about twice as fast as compiling via C, and is on a par for
     run-time speed (except in FP-intensive programs).

   - Implicit parameters (i.e. dynamic scoping without the pain).

   - DEPRECATED pragma for marking obsolescent interfaces.

   - In the wake of hslibs, a new package system for
     libraries. -package should now be used instead of -syslib.

   - Result type signatures work.

   - Many tiresome long-standing bugs and problems (e.g. the trace
     problem) have been fixed.

   - Many error messages have been made more helpful and/or
     accurate.

+ Windows problem
==================

ALERT: For reasons as yet not understood, as of January 2001 Cygwin's mingw
package has a problem that causes GHC-compiled binaries to be built
incorrectly. The fix is to ensure that your mingw package is dated 20001111
(you can set this in the Cygwin installer). See the installation guide for
more details.


+ Mailing lists
================

We run mailing lists for GHC users and bug reports; to subscribe, use
the web interfaces at

	http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
	http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

There are several other haskell and ghc-related mailing lists on
www.haskell.org; for the full list, see

	http://www.haskell.org/mailman/listinfo/

Please send bug reports about GHC to glasgow-haskell-bugs@haskell.org;
GHC users hang out on glasgow-haskell-users@haskell.org.  Bleeding
edge CVS users party on cvs-ghc@haskell.org.


+ On-line GHC-related resources
================================

Relevant URLs on the World-Wide Web:

+ How to get it
================

The easy way is to go to the WWW page, which should be
self-explanatory:

	http://www.haskell.org/ghc/

Once you have the distribution, please follow the pointers in the
README file to find all of the documentation about this release.  NB:
preserve modification times when un-tarring the files (no `m' option
for tar, please)!


+ System requirements
======================

To compile the sources, you need a machine with 32+MB memory, GNU C
(`gcc'), `perl' plus a version of GHC installed (3.02 at least).  This
release is known to work on the following platforms:

  * i386-unknown-{linux,freebsd,netbsd,cygwin32,mingw32}
  * sparc-sun-{sunos4,solaris2}
  * hppa1.1-hp-hpux{9,10}

Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:

  * i386-unknown-solaris2
  * alpha-dec-osf{2,3}
  * mips-sgi-irix{5,6}
  * {rs6000,powerpc}-ibm-aix

The builder's guide included in distribution gives a complete
run-down of what ports work; an on-line version can be found at
