More wibbles, sigh.  Must have been typing with my elbows when I made
that change.

CmRunDeadlocked no longer exists

Fix wibbles in previous commit.

Strip whitespace from the beginning of the line when looking for
OPTIONS pragmas.

Deadlock is now an exception instead of a return status from
rts_evalIO().

The current behaviour is as follows, and can be changed if necessary:
in the event of a deadlock, the top main thread is taken from the main
thread queue, and if it is blocked on an MVar or an Exception (for
throwTo), then it receives a Deadlock exception.  If it is blocked on
a BLACKHOLE, we instead send it the NonTermination exception.  Note
that only the main thread gets the exception: it is the responsibility
of the main thread to unblock other threads if necessary.

There's a slight difference in the SMP build: *all* the main threads
get an exception, because clearly none of them may make progress
(compared to the non-SMP situation, where all but the top main thread
are usually blocked).

Attempt to fix the problems with missing instances once more.

The current problem is that in the case where a ModDetails is being
constructed from its interface (in compilation manager modes) we
weren't getting any instances because the instances are gotten from
the [InstInfo] returned from tcInstDecls1, which only contains
*source* instance declarations.  Fix: return a list of DFuns defined
in the current module from tcInstDecls1, to be plugged into the
ModDetails later.

Also: revert the previous change to the isLocalThing predicate,
because now we really want to know which dfuns come from the current
module.  The comment about the iface_dfuns containing only package and
local instances is incorrect in batch-compile mode, because we also
demand-load stuff from home package interfaces, so I deleted this
comment and fixed up some of the other commentary.

Fix for a change in CPP's behaviour in gcc 2.96 relative to 2.95.
Unlit used to inject '# <line> <file>' at the beginning of the output
file, but in gcc 2.96 this is ignored.  Instead we have to inject
'#line <line> <file>', which in turn means that GHC's lexer has to
understand this kind of pragma in addition to the plain '#' form, in
the case when we aren't running CPP after unlitting.

Import wibbles

assume bash (and not ash) is used with mingw

tcInstDecls1: partition up interface instances using isHomePackageThing rather than isLocalThing

added isHomePackageThing :: NamedThing a => a -> Bool

For AR and LD, transform "/cygdrive/<drive>/..." paths to "<drive>:\..." --
enables the use of mingw-based GNU Make.

bash behaviour re: quoting and backslashes has changed (win32), cope.

- removed KludgedSystem; no longer needed.
- be path separator savvy.

Added an intro to the workings of the desugarer and details about the pattern
matching compiler.

updates & fixes to hc-bootstrapping story; from Thomas Nordin

add HSstd{1,2}.o to INSTALL_LIBS (mingw only)

Better off if GhcBinDistShScripts is just empty on mingw plats

mingw only: associate FPish icon (nicked from Hugs) with
the GHCi wrapper app.

'std' now also needs user32 (under win32)

First cut at enhancing the facilities for manipulating the scope in
GHCi.  The scope now consists of

  1. the full top-level scope of zero or more interpreted modules
  2. the exports from zero or more modules
  3. the temporary bindings

The sets 1 & 2 are manipulated using an extended :m command: eg :m +A
will add module A to either set 1 or two depending on whether A is
interpreted, and :m -A will remove it.  The user interface may change,
pending feedback from the punters on the mailing list.

'Prelude' is automatically added to the scope if set 1 is empty and
set 2 doesn't already contain it.

We now cache the GlobalRdrEnv for the current scope between
evaluations in the InteractiveContext, and also the current
PrintUnqualified setting (which also depends on the scope).

Cvs: ----------------------------------------------------------------------

Back out previous fix, I've hacked it in a different place which is at
least closer to the source of the problem.

Don't add -package-name if $(PACKAGE) == "rts".  THis is a HACK and we
need to fix the mess in ghc/rts/Makefile properly.

Fix a problem which lead to home-package instances ending up in the
package instance table in GHCi, which results in strange duplicate
instance errors when reloading modules.  See the comments for details.

Make better use of the -M<size> setting under Win32. Use it to guide
the amount of VM to reserve -- the default is (still) 256M, but the
user will now have a way of overriding this setting.

Track PrimOp changes.

On the alpha, __divq() in libc.a clobbers $s6, so StgRun() needs to save
$s6.  While we are at it, let us save $f8 and $f9 as well.
