replace one instance of ar with $(AR).

Out of memory should be a belch(), not a barf().

      Fix a long-standing egregious CorePrep bug
	----------------------------------

	**** Merge to Stable branch ****

CorePrep was eta-reducing

	\x -> (# a,x #)
to
	(#,#) a

which is utterly wrong.  Easily fixed though.

Reformat this section a bit, and add a note about the poor performance
of mutable arrays in the garbage collector.

Correct file names in RULES documentation

threadLabels: not public

protoize heapCheckFail()

drop Main.h

no longer used

Correct error in MacOS-specific configure code.

Fix a profiling crash on Windows.

fprint_ccs used snprintf() to avoid overflowing a buffer; on mingw32
where snprintf() doesn't exist we were just using the straight
sprintf(), which inevitably lead to a crash.  Rewritten to use a
homegrown non-overflowing string copying function - it actually looks
nicer now, anwyay.

This should have been committed along with rev. 1.36 of Main.c (and
others) yesterday, but for some reason it got left out.

Change the way Main.main is run, so it now doesn't force the return
value.  Now 'main = return undefined' will run and exit successfully.

The change affects finalizers too - but since they have type IO (), it
won't do any harm not to evaluate the ().

Fix wibble in previous commit (fixes broken bootstrap)

Fix for lexing of floating point numbers.  '9e2' should be a float.

Noticed-by: Ross Paterson.

Haskell quiz:  what should this program do?

  main = return undefined

answer: run to completion and exit successfully.  GHC erroneously
evaluates the returned value from main, which causes this example to
fail with an uncaught exception (the evaluation is even done outside
of the main exception handler!).

Support for contexts on data types and records from Derek Elkins.

Fix tryM for GHC 5.00.x and 5.02.x.

Add comment about lack of instance-support in .hi-boot

- Remove mention of MutableByteArray and ByteArray

- Add section on memory allocation in the FFI, with emphasis on how
  GHC's implementations of the various kinds of allocation perform.

GHC has parsed

	data T String = T String

without complaint, ever since day 1!  This led to consequential
incomprehensible messages.  The fix is easy.

Document external core a bit more

Restructure documentation about undecidable instances

Buglet in external-core parsing

Use STK_CHK_NP rather than STK_CHK_GEN in the entry code for AP and
AP_STACK thunks.

The reason is that if the check fails, on return the closure might
have been blackholed (perhaps due to lazy blackholing, or even because
another thread has entered it), so we *must* enter the closure to
continue, rather than just continuing at the original entry point.

All compiler-generated thunks do this anyway, I think these are the
only cases of thunks which don't follow the rule.

Thanks to Robert Ennals for spotting, and correctly diagnosing, the
bug.

Fix typo

Fix compilation problem on mingw32

Minor wording

Update docs on class method types

Markup glitch

Oops, byteCodeGen should get the bindings from CorePrep, not CoreTidy
(should fix last night's GHCi breakage).

some rearrangement.

also install libraries.html

notes for Hugs

generate docs/libraries.html

Split off the hierarchical libraries page, so the Hugs folks can use it too.

Duh.  hsc2hs should be in $(GhcBinDistShScripts), not
$(GhcBinDistBins), otherwise it doesn't get the right directories
tacked on the front at installation time.  Strange that nobody
complained that hsc2hs wasn't working from a binary dist *shrug*.

Make it compile again with 5.04.x

Fix compilation breakage with GHC 4.08.x.

win32/Ticker.c:startTicker(),

  Needed to work with Win9x's impl of CreateThread().
