restore the two-space sanity checking code.

tidy up conditionals a bit.

Add Sven's qsort foreign export dynamic test.

allow for per-program LD_OPTS.

Give a more informative error message in rts_checkSchedStatus().

Add uncaught exception test.

raisezh_fast now handles uncaught exceptions cleanly.  The affected
thread is marked as Killed, and if it is a main thread then
rts_evalIO() will return ThreadKilled as it should.

comment-only clarifications; Killed means "uncaught exception".

note that a return status of Killed means "uncaught exception".

Adding trivial entry counter.

o Adding simple counter for number of enters
o Inc version number
o Adding the start of support for mdo
o Wibble

Trying again to remove old version of prelude

Fix bug in rts_apply when profiling.

This fixes Sven's foreign export dynamic/profiling bug.

Fixes to commitBuffer and commitAndReleaseBuffer to maintain the
invariant that we never leave the handle buffer in a completely full
state.  This fixes the crashes seen in recent Sparc builds.

Found with help from:  Electric Fence &:-)

Allow tests to be omitted (OMITTED_RUNTESTS), so that tests which are OS-
specific can be omitted on other OSs.

Numerous tweaks to remove out-of-date constructs and make tests Windows-
friendly.

fix bug in new -ofile stuff: we were missing a '.' between the tmp
file root and the suffix.

Use get_itbl instead of direct access to info field in
removeIndirections. This "worked" only because the probability of
hitting an indirection-like closure by chance is 5:65531 on 32bit
platforms. :-) But HOpenGL once again managed to expose this bug...

- revised for ghc 4.07; added suggestions from Pixel <pixel@mandrakesoft.com>
- added profiling package
  [these are named ghc-prof-<version>.<arch>.rpm]

Don't use coercion RULES with litlits (e.g. int2Word ``42''), once
again found by *the* GHC test, HOpenGL + Quake level viewer. :-)

Include Weak.h to remove a warning

I've bitten the bullet and cleaned up the mess around Readline. There
are actually questions to answer by autoconf:

   * Are the headers available for compilation?
   * Are the libraries (and which) available for linking?

Note that in the second case it should be the libraries on the machine
which GHC is *installed* on, not the ones on which it was compiled.
GhcLibsWithReadline is now automagically set if the headers are found,
but this can still be overridden.

/tmp/msg

Bumped the maximum size of tuples from 37 to 62. If this is not
wanted, use PrelTup_HC_OPTS+=-DNO_LARGE_TUPLES in build.mk.

Further steps towards an empty build.mk:
   * GHC is now built with -O by default
   * hslibs/tools now use GhcLibToolsHcOpts, again -O by default

Add loop test

Remove a way to make the simplifier go into an
infinite loop.   This has been there for some weeks;
and George's UniForm tickled it.  I'm amazed nothing
else has done so.  I'll add a test.

The bad case happened when you go

	let xs = 1:xs
	in
	foldr k z xs

Then we kept firing the foldr/cons rule.

Solution: we don't attach an unfolding *at all* to
loop breakers (Simplify.completeBinding)

First I forgot to commit all the files for the
Java support.  Then I spoke the wrong CVS command.
This commit just adds the log message!

--------------------------
Add support for Java generation, written in
a lightning day with Erik Meijer

	ghc -J Foo.hs

will do the business, generating Foo.java

The code is in a new directory, javaGen/, so
you'll need to cvs update -d.

I've reorganised main/CodeOutput quite a bit; it
is now much much tidier, and will accommodate new
languages quite easily.

I've also fiddled with the flags that communicate
between the driver and hsc.

GONE:	-S=  -C=

NEW:	-olang=xxx	output language xxx
			xxx can be: C, asm, java

	-ofile=xxx	put the output code in file xxx


BEWARE that I might have broken some of the more
cryptic stuff in ghc.lprl.

Finish TcClassDecl

To avoid potential collisions between different modules, prefix the
names of the C stubs with the module name.

I'm not sure if the last commit of MkId.lhs was incorrect or
incomplete. Anyway, to build hsc I've commented out the now
superfluous parameter for mkDictSelId (marked with "SUP:???").

Package util now depends on package posix, too.
NOTE: To get Readline up and working, -lreadline and one of
-lncurses/-lcurses/-ltermcap has to be inserted, too, but this has to
be autoconf-ed somehow (later...)

Update this file to the one on the web site, and add Simon's latest
notes about using the cvs- lists for bug reports about the cvs
sources.

Print out cost centre names as C strings (using proper escaping for
special characters etc.).

Improved rules for stubs. Not perfect yet, but better than before.

add	pprStringInCStyle :: String -> SDoc
(we already have a FAST_STRING version but not one for plain Strings).

Fix for initModules when unregisterised.
