set $(HC) to the inplace ghc driver script.

Swap ticky column order

Allow unboxed tuples with zero components in unfoldings, CPR seems to
generate them occasionally (perhaps it shouldn't - there is very
little difference between returning () and (# #)).

oops: unbreak non-ticky compiles

Add a test for scoped type variables

Crude allocation-counting extension to ticky-ticky profiling.

Allocations are counted against the closest lexically enclosing
function closure, so you need to map the output back to the STG code.

#ifdefs for bootstrapping

add a bunch of #ifdefs so we can bootstrap again

Don't use variables beginning with underscore, 3.02 doesn't grok them.

install (INSTALL_PROGS): a ; too many

Disable object loading until Hugs/GHC class/instance sync is done.

Minor library handling mods to make nofib work again.

Try and make finding of Prelude libraries for hugs a bit saner.
Guess (badly) the absolute pathname to the hugs executable, and
use that to derive the location of the default library.

use $(GHC), not $(HC)

Added the {index,read,write}{PrimTy}OffForeignObj ops to Foreign's
export list + upd. the docs on same a little.

Incorporate some fixes for Hugs

While fiddling around with concurrency & exceptions this afternoon, I
realised an important property of raiseInThread: it is synchronous.
The exception is raised immediately, and doesn't sit in some queue
somewhere waiting to be raised at a later date.

This is important if you have eg. two threads that can kill each
other.  We can guarantee that only one of the threads gets to kill the
other, under no circumstances can there be two killThreads fired in
opposite directions at the same time.

Documented this.

Change that slipped through the net in the recent build system changes.

Improved on the install rules for libexecs and bins a little
(at least from a Win32 pov - you can now install "happy.bin"
without trouble.)

Support for generating a VERSIONINFO resource that can be pinned
onto generated DLLs and EXEs (Win32 specific.)

Delay shutting down WinSock until exit() time

Always prepend `#! $(INTERP)' to a script, even if we're BIN_DISTing.
It doesn't do any harm, and means that we can execute the BIN_DIST
version of a script from the build tree, provided it doesn't depend on
any global paths.

GHC versions are now of the form AA.BB.C, where AA is the major
version, BB is the minor version, and C is the patchlevel.

Part of this commit accidentally ended up in an earlier commit to
fptools/ghc/mk/version.mk, which contains some comments on the version
rationale.  Excerpt:

# ProjectVersionInt does *not* contain the patchlevel (rationale: this
# figure is used for conditional compilations, and library interfaces
# etc. are not supposed to change between patchlevels).

i.e. a patchlevel is for bugfixes only, no new features or
interface-changing changes.  Unfortunately, we made this mistake in
4.04pl1, and won't be making it again.

Build System Cleanup
--------------------

This commit is intended to clear the way for automatic RPM building.
In particular, the idea is that 'make install' doesn't build anything,
so you can do

	make install prefix=/some/tmp/prefix

to install everything in /some/tmp/prefix, but leave the hardwired-in
install directories the same.

For scripts that depend on the install dir (currently just the GHC
driver and mkdependHS), we now build two versions: <script>-inplace,
which is used for running the script from the build tree, and
<script>, which is the to-be-installed version.

NOTE: binary distributions are now a little bit trickier to build.
You *must* include the line "BIN_DIST=1" in your build.mk if you
intend to make a binary distribution from the current build tree.
This is because certain scripts have to be built differently, and we
don't rebuild them when doing 'make binary-dist' anymore (since 'make
binary-dist' just does a 'make install' with a re-targetted prefix,
just like the RPM builder).

Other changes

	- the binary-dist machinery is now all in fptools/Makefile
	- removed a gratuitous $(package)-$(version) level of
	  directories from the binary distribution.
	- binary distributions are now placed under the package
	  name, rather than fptools/fptools.
	- various other minor cleanups.

--with-ghc-hc is now --with-hc (to be used as the "locally installed
Haskell compiler" for all projects).

Remove hstags for now.

(keving)

Much simplified and beautified CPR analysis code.  (And also much
shorter, we'd better write this up before it disappears).

Added (constant) functions to the abstract domain. Note that
Fun^n Bot (n >= 1) == Bot and likewise for Top

Treats divergent computations as Bot (rather than Top as previous) so
non-divergent paths dominate which allows us to generate more accurate
CPR info (see e.g. chr).

We use the result of strictness analysis to tell us if an Id is
divergent (when applied to sufficient args), therefore we should run
after the strictness analysis pass.

Flatten out the tuple of bounds in the Array, MutableArray and
ByteArray datatypes.  This improves performance of heavy array
manipulations quite significantly.

Service signal handlers if we get an EINTR from select(2).

allow raising exceptions in threads blocked on I/O or time delays

hstags doesn't work any more - disconnect it

avoid giving 'sub's empty parameter lists

For strftime()'s format string, stay within the bounds of ISO/ANSI C

Simplified the interface between CPUTime.getCPUTime and getCPUTime()
