add MaxOSX version of mmap.

Merge rev. 1.18.2.2

merge recent changes from before-ghci-branch onto the HEAD

Made message for exceeding 128Mb of heap on Windows more helpful, and
only abort when this limit is exceeded, not on first memory allocation!

barf when a DLLized RTS tries to allocate a 2nd Windows monster block;
is_heap_alloced stops working at this point. No problem for the static
build.

Port to OpenBSD from Thomas Nordin.  Please merge with 4.08 (you'll also
need the new config.guess and config.sub from the previous commit).

Stopped getourtimeofday() being called under mingwin.
MBlock.c: changed one instance of 128 * 1024 * 1024 into SIZE_RESERVED_POOL
and added a TODO comment (bug in is_heap_alloced(), which won't work if
more than one megablock is ever allocated).

freebsd3 ==> freebsd

Add NetBSD/x86 support.

Magic Constant Removal

HPUX fixes.

Added is_heap_alloced() to the API - returns true if an address is
within the range of addresses that we've been given back from the
OS.

Only needed for Win32 DLLs, so it's only defined when compiling up
a Win32 RTS DLL.

Copyright police.

ifdef fix

Added osf3 guess

Don't bomb out with "Dont know where to get memory from on this
architecture" on Win32.

'Native' Wni32 implementation of getMBlock(). Also added a Win32 impl.
of freeMBlock() in case that ever should become useful.

Forgot to commit this before Christmas...on Win32 platforms use
VirtualAlloc() instead CreateFileMapping()&friends to ask for
mega-blocks from the OS. Windows 95-friendlier.

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.

Move 4.01 onto the main trunk.
