Fix bogus uses of C variable stable_ptr_table exposed by recent fix to
C backend.

Warning police (unused parameter)

Nuked dead code

No -optc prefix fot GhcRtsCcOpts needed

Fix comment

ATTENTION: Make it compile again, but only via a wild and probably
wrong guess which might break GHCi. SimonM, please have a look at
this. (Who broke it should fix it! :-)

tweak to handle ghc-6.1 compilation. Merge to STABLE

added ghc_ge_602. Merge to STABLE

Don't split in here

Fix a comment

enable splitting on x86_64

splitting support on x86_64

fix uses of stderr

Switch to a manual-reset event for the completed-console-event object;
with auto-reset, we ran the risk of leaving it in a signalled state.

Merge to STABLE.

Switch away from using _spawnv() to CreateProcess(); the former has the
annoying 'feature' that it quits upon Ctrl-C, leaving its child in the
background. Use CreateProcess() instead and avoid the Ctrl-C issue by
having the wrapper let go of its console before waiting for the sub-process
running GHCi to exit.

This still doesn't fix the issue of Ctrl-C handling when the 'ghci' wrapper
is invoked from a cygwin-based bash. cmd.exe users will hopefully see
an improvement in behaviour though.

Merge to STABLE.

[mingw only]
Better handling of I/O request abortions upon throwing an exception
to a Haskell thread. As was, a thread blocked on an I/O request was
simply unblocked, but its corresponding worker thread wasn't notified
that the request had been abandoned.

This manifested itself in GHCi upon Ctrl-C being hit at the prompt -- the
worker thread blocked waiting for input on stdin prior to Ctrl-C would
stick around even though its corresponding Haskell thread had been
thrown an Interrupted exception. The upshot was that the worker would
consume the next character typed in after Ctrl-C, but then just dropping
it. Dealing with this turned out to be even more interesting due to
Win32 aborting any console reads when Ctrl-C/Break events are delivered.

The story could be improved upon (at the cost of portability) by making
the Scheduler able to abort worker thread system calls; as is, requests
are cooperatively abandoned. Maybe later.

Also included are other minor tidyups to Ctrl-C handling under mingw.

Merge to STABLE.

oops;supposed to have been included with revert-back-to-__stginit-for-mingw commit

resetStaticObjectForRetainerProfiling(): warning wibble

Until the GHCi linker is made capable of handling .ctors sections in
PEi object files, stick with __stginits. Being a bit sloppy by
using 'mingw32_HOST_OS' to test for this.

Fix creation of raise_info closures: they're THUNKs

evacuate(): fix THUNK case

checkSanity: fix bug in nursery checking

SAVE_EVERYTHING: for some reason we used R10.w rather than R10 in this
macro, which just broke with the change to the C backend.

- Now that labels are always prefixed with '&' in .hc code, we have to
  fix some sloppiness in the RTS .cmm code.  Fortunately it's not too
  painful.

- SMP: acquire/release the storage manager lock around
  atomicModifyMutVar#.  This is a hack: atomicModifyMutVar# isn't
  atomic under SMP otherwise, but the SM lock is a large sledgehammer.
  I think I'll apply the sledgehammer to the MVar primitives too, for
  the time being.

rtsSupportsBoundThreads, isThreadBound: these should return rtsTrue
for SMP too.

pprLit: when printing a CLabel, prefix it with '&'.  This ensures we
get the address rather than the value, in the case when the C label
refers to a variable (as might be the case if it is from a foreign
import, for example).

Remove bogus cut-n-pasted comment

SMP: the rest of the changes to support safe thunk entry & updates.  I
thought the compiler changes were independent, but I ended up breaking
the HEAD, so I'll have to commit the rest.  non-SMP compilation should
not be affected.

Add a comment about possible improvement to the THUNK_SELECTOR
algorithm, from discussion with Ian Lynagh

Various fixes to ghcprof, from Christian Maeder <maeder@tzi.de>.  Thanks!

Fix hi-boot interface-finding code

SMP: thunks get an extra header word so that the payload doesn't
occupy the same space as the updated value.  This is the sum total of
the changes to compiler/, which are pleasingly few.

Allow args to be passed to GHC from runghc

  syntax: runghc [-f GHCPATH] [GHC-ARGS] FILE ARG...

ghcprof is a perl script, not a binary

Remove bogus code: the mutable list does not need to be rebuilt during
compaction.  It just needs to be updated, which is already happening.

(fixes crashes in compacting collection; I think a different fix is
required for STABLE, though)

Update to match ClosureTypes.h

remove gaps in the closure type sequence, and add a big warning comment

modInfoExports, TypecheckedSource and ParsedSource are exported.
Added modInfoPrintUnqualified function.

- DriverPipeline.compile: report errors in GHC_OPTIONS pragmas using the
  Message callback, and give them a proper line number.

- GHC.checkModule: read the GHC_OPTIONS pragma, and report errors
  appropriately.
