- __HASKELL1__ is now 5 (was 4).  Surely not the last word in
  Haskell98 CPP symbols.

- Fix stats munging for new RTS.

x86: only add -fomit-frame-pointer when compiling .hc files.  It gets
in the way of debugging for normal .c files.

Added a generational garbage collector.

The collector is reliable but fairly untuned as yet.  It works with an
arbitrary number of generations: use +RTS -G<gens> to change the
number of generations used (default 2).

Stats: +RTS -Sstderr is quite useful, but to really see what's going
on compile the RTS with -DDEBUG and use +RTS -D32.

ARR_PTRS removed - it wasn't used anywhere.

Sanity checking improved:
	- free blocks are now spammed when sanity checking is turned on
	- a check for leaking blocks is performed after each GC.

Added -fno-asm-mangling.

Move 4.01 onto the main trunk.

add_syslib: turn off -syslib loop checking

Tidied up -syslib handling, and in the process require the use of Perl5

Misc changes to cope with compiling code containing foreign decls that also causes C stubs to be gen'ed

- turn on cloning in first simplifier pass to ensure
  that the output from desugarer&TC gets unique binders
  before the Simplifier TransformFest really gets going.
- Solaris specific: include -lsocket in the linker
  command line when using -syslib misc.
- pipe through to compiler the new option -funfold-casms-in-hi-file.

-syslib win32: Do the right thing if using a non-installed compiler

- (optionally) put hsc command-line options in a temporary file.
- -syslib win32 support

Sigbjorn forgot a semicolon :-)

Expose -fallow-overlapping-instances to the world

Get the concurrent syslib included for free, when -gransim\'ing or -parallel\'ing

- remove $opt_UnfoldingUseThreshold, it's a per-compilation flag now
  (not per-simplification)

- pass through all -funfolding-.* flags, so we can get at the rest

hscpp no longer supports -genSPECS

move update analyser into -O2 optimisations.

Renamed conc syslib to concurrent

-O setup: enable -fclone-binds in simplifier pass immediately
          preceeding -ffull-laziness (see comment)
new option: -hi-with-<section> to selectively output contents of
interface file.

remove obsolete ToDo.

enable specialiser

Added -optp for passing options to hsp

cygwin32: if no -o given, tell linker to create main.exe

- InstLibDir --> InstLibDirGhc
- ${INSTALLING} --> $INSTALLING

inserted missing semicolons.

Remove redundant PROJECT{VERSION,NAME,PATCHLEVEL} in favour of
ProjectVersion etc. from config.mk.in.

misc syslib related fixes

-syslib conc doesn't have any cbits.

Warn specially if users should supply interface files
on the command line.

Library re-organisation:

All libraries now live under ghc/lib, which has the following structure:

	ghc/lib/std    		--  all prelude files 		(libHS.a)
	ghc/lib/std/cbits

	ghc/lib/exts		-- standard Hugs/GHC extensions (libHSexts.a)
				-- available with '-fglasgow-exts'

	ghc/lib/posix		-- POSIX library                (libHSposix.a)
	ghc/lib/posix/cbits     -- available with '-syslib posix'

	ghc/lib/misc		-- used to be hslibs/ghc	(libHSmisc.a)
	ghc/lib/misc/cbits	-- available with '-syslib misc'

	ghc/lib/concurrent	-- Concurrent libraries		(libHSconc.a)
				-- available with '-concurrent'

Also, several non-standard prelude modules had their names changed to begin
with 'Prel' to reduce namespace pollution.

	Addr      ==> PrelAddr     (Addr interface available in 'exts')
	ArrBase   ==> PrelArr
	CCall     ==> PrelCCall    (CCall interface available in 'exts')
	ConcBase  ==> PrelConc
	GHCerr    ==> PrelErr
	Foreign   ==> PrelForeign  (Foreign interface available in 'exts')
	GHC       ==> PrelGHC
	IOHandle  ==> PrelHandle
	IOBase    ==> PrelIOBase
	GHCmain   ==> PrelMain
	STBase    ==> PrelST
	Unsafe    ==> PrelUnsafe
	UnsafeST  ==> PrelUnsafeST

Split -fwarn-unused-names into

	-fwarn-unused-imports	 Warn about unused explicit imports. (in -W)
	-fwarn-unused-binds	 Warn about unused bindings	     (in -W)
	-fwarn-unused-matches    Warn about unused names in pattern matches
				 (not as useful, relegated to -Wall)

* [cygwin32]: If no output file is given when linking, default to main.exe
* warn about SCCs being dropped when compiling with -prof -auto{-all}

Restore perl4 compatibility.

Append -lnsl when using -syslib ghc on Solaris2 boxes (BSD nwork support.); -w as synonym for -Wnot; pass -fsignatures-required through to compiler proper.

Add -fwarn-duplicate-exports to default warning set

posix misspelled

Replace use of map() with foreach, to make the driver perl4 compatible
again.

Quote -#include opts when passing them on (to mkdependHS); silently add ghc syslib with posix (it depends on it.)

oops, correct a comment.

move -fwarn-incomplete-patterns into -W (it's not as likely to
indicate an error as -fwarn-overlapping-patterns), and add
-fwarn-unused-names to -W in case it gets implemented one day.
