only pop explicit layout contexts with '}'.

print the compiler version on the same line as the compilee version;
looks a bit tidier.

Header file for an alternative bignum implementation, which is in
interpreter/sainteger.c.  Currently used by STGHugs.
Temporary -- until we resolve GMP licensing issues.

Re-jig some stuff in here so it doesn't look like you need so many
tools to build GHC.

Added maxPrecedence

Added needed includes of SchedAPI.h

Whoops, add index terms too.

Add -ddump-most and -ddump-all, with the obvious meanings.

Redo previous commit to cut down on the use of COMPILING_RTS where
possible - SchedAPI.h is now an RTS internal header file which
RtsAPI.h no longer includes.

Don't include RtsAPI.h when compiling RTS.

Temporary workaround for problem which caused the following program

  main = putStrLn ("aa" ++ IOExts.trace "bb" "cc")

to deadlock - when the (untouched) stderr is evaluated (which
IOExts.trace forces), it will touch stdout (see code for details of
why), but it has already been locked by putStrLn. Boom - game over.

This temporary 'fix' is, to put it kindly, in the fancy-footwork
category as it doesn't solve the problem, but merely turns it on its
head. Instead of stderr depending on stdout, stdout now depends on
stderr, so the following program will deadlock

  main = hPutStrLn stderr ("aa" ++ myTrace "bb" "cc")

  myTrace msg v = unsafePerformIO $ do
     putStrLn msg
     return v

The 'theory' is that this is far less likely to occur in practice than
the other way around.

The next step / real solution would be to give up the lock on an
output Handle while filling up its output buffer. However, that
requires ripping out / re-org'ing a fair bit of buffer management
code, which I'll delay doing.

Remove -#include "RtsAPI.h" - you now get it for free.

Stg.h contains all the defs and protos that are visible when compiling
.hc code (==> .hs code). Augment this set with the externally visible
RTS API.

Tidied up the handling of the code that emits the precedence level
predicates that gets used in applications of showParen and readParen.

Two new Dark Corner regression tests:

- testing the derived Show&Read instances for constructors with
  a field label that is a varsym rather than a varid.
- check that the default fixity & assoc of an operator is 'infixl 9'.

New option, -fail, to indicate failure (whatever the return code).

Make sure that instance gates have their home modules
loaded by RnIfaces.getImportedInstDecls.  This was causing
Kevin Atkinson's missing-instance bug.

* If a field label is a 'varsym', wrap parens around it when
  Show'ing and Read'ing it back in.

* If there's no fixity decl for a 'consym', the default is
  for it to be left-assoc.

Don't use WinSock under cygwin

Don't compile in WinSock support under cygwin

exitWith: don't call exit(), but use the RTS' shutdownHaskellAndExit()

New RTS entry point, shutdownHaskellAndExit(), which does what the name
implies - used when you want to exit from within Haskell code (e.g.,
System.exitWith.)

Remove final fflush() - it seems to be incompatible with recent
releases of Linux's libc implementation, and we don't use stdio in any
case.

The allocator for mega groups now checks if consecutive megablocks on
the free list are contiguous in memory. The omission of this check
caused all kinds of funny runtime errors and took away at least five
happy years of my life...  :-{

8-bit clarity

Make this more Haskell 1.3-insensitive

Allow the following (not strictly H98) construct:

    do
	blah
	e $ do
	blah

This doesn't break any existing code, just allows more programs
through.  Only the semantics for layout after a 'do' have changed.

Add a test for deriving Show (f (f a)); makes Hugs hang

Make the r.u.n message happen only with -DDEBUG

Back out a change that creeped in by mistake.

Clean out objects generated from assembly files.

Made the compilation of the RTS almost warning-free and improved the
output of some "barf"s in the garbage collector . This is part of my
epic crusade against "scavenge_mut_list: strange object?"... :-(

Suppress warnings by making some static symbols extern.  Sigh.

Someone with a big stick told me to remove -ddump-cpranalyse
Use -ddump-cpranal instead.

CPR Analysis Mark 2. Slightly more elegant,  and (I believe) now
copes correctly with references to CAFS and non-top level function
bindings.

(keving)

Add dump-cpranal to agree with the users_guide.  dump-cpranalyse will
still work but is deprecated and could be removed by someone with
a bigger stick than me.

Back out changes for "specialid"s.  It didn't work this way: there was
a conflict in the grammar.

Add explanatory comments

Fix SetLevels so that it does not clone top-level bindings, but it
*does* clone bindings that are destined for the top level.

The global invariant is that the top level bindings are always
unique, and never cloned.

Some renamer fixes

* Correct the defn of Rename.isOrphanRule (caused a Sergey bug)

* Tidy up the Rename.implicitFVs stuff
