Update the documentation on --make mode to indicate that multiple
sources/modules can be given on the command line, as well as multiple
object files.

Simplify the bitmap-generating code by collecting all the pointer
words rather than all the non-pointer words, and then subtracting
these from a bitmap made of all ones.  This is simpler because we only
have to look in the bindings, rather than combining information from
bindings and the free stack slot list.

Expand bitmaps to cover the full size of the stack frame.  Previously
the bitmap would stop at the last non-zero bit, which might shorten
the bitmap by one or more words.  The behaviour used to be correct,
but with the eval/apply changes bitmaps must now cover the entire
stack frame rather than everything up to the last non-pointer word.

Declare stg_BCO_entry.  (this should have been committed with rev. 1.4
of utils/genapply/GenApply.hs).

--------------------------------------------------------------
	Several small but tiresome things shown up by Template Haskell
	--------------------------------------------------------------

1. Make the 'knot' in TcRnDriver much smaller; in fact move it to
   TcIfaceSig.tcInterfaceSigs.  Reasons
	a) much tidier
	b) avoids a loop in Template Haskell, when we try to run
	   an expression during type checking (when the knot is
	   not fully tied)

   See comments in TcIfaceSig

2. Stop typechecking if tcGroup fails.  Reason: otherwise tcLookup can
   fail in the next group.

3. Catch linking errors more gracefully when running a splice (in TcSplice)

Small extra tc-trace

Make HscMain.compileExpr run lint if -dcore-lint is on

1.  Arrange that -ddump-tc-trace will print out the exception caught by tryTc

2.  Make forkM a bit quieter, unless -ddump-tc-trace is on.

Spelling

dieWith uses ProgramError, not UsageError

---------------------------------------------
	Try slightly more aggressive rule application
	---------------------------------------------

Switch on AlwaysActive rules even in SimplGently.  This should
make some TH programs a little better, but it's not a big deal.

--------------------------------
	Make ModLocation have a FilePath
	instead of (Maybe FilePath) for
	the object-file location
	--------------------------------

This generally tides things up, and makes ml_obj_file more like
ml_hi_file.

Furthermore the ml_obj_file field gets filled in even when we
initially expect just an .hi file.  This is important for Template
Haskell.

Disable the version check on the .hi file for --show-iface.  This
means that it can be used on .hi files for other "ways" (eg. profiled)
without having to resort to using the undocumented -buildtag option.

Add a handy hint for finding the correct fully-qualified original
names for entities in .hi-boot files.

The FUN application code is wrong when entering a BCO, because the BCO
entry code assumes a stack-only calling convention.  Use the PAP entry
code instead, which also uses a stack-only convention.

Prefix a double-underscore to a variable in a macro, to avoid conflicts.

Darwin: Replace "g" constraint by "r" in inline assembly, otherwise it won't compile without -O

Imports cleanup

Nuked prototype for non-existent function 'RevertCAFs'. Even if this
should be the same as ghc/rts/Storage.h's 'revertCAFs', it would still
be a strange place...

-#include cleanup. What we really need here are additional prototypes
for 'getAllocations' and 'revertCAFs', but these are only available
via RTS headers. I'm not sure if -#including them somehow would be OK,
so I left this out. A few lines of documentation who is allowed to
#include (or -#include) what would be helpful...

Load Mac OS X - style "frameworks" given on the command line (-framework XXX)

Mac OS X doesn't have the sysconfig constants _SC_GETPW_R_SIZE_MAX and _SC_GETGR_R_SIZE_MAX, so add a configure check

Add the #includes from the rts package to the stub .c file.

Prior to rev. 1.42, we used to add all the #includes from all enabled
packages, together with any -#include options from the command-line.
But since this is auto-generated code and we know exactly which
#includes are required, this was overkill.

In rev. 1.42, all #includes except RtsAPI.h were removed from the stub
.c file.  This was incorrect, because the stub file refers to some
entities defined in other RTS header files (the StgStablePtr type, and
deRefStablePtr() for example).

This change adds the header files from the rts package to the stub .c
file, fixing some recent test breakages.

Add more M4 quoting (required by autoconf 2.57)

Fixed #ifdefery for GCC >= 3.x

GHCi needs to link in packages eagerly if they're specified on the
command line.

Terrible hack to restore CAF handling behaviour in GHCi (it's
currently broken).

The story used to be this: in newCAF(), if the CAF is in dynamically
loaded code, then we save the CAF's info ptr in a spare slot in the
closure, and add the CAF to the caf_list.  The GC will retain
everything on the caf_list.  At any point the CAFs can all be reverted
by replacing their info pointers from the saved copies.

CAFs need to be retained for GHCi because they might be required in a
future execution; an optimisation would be to avoid retaining the CAFs
if we're in "revert mode"; i.e. the CAFs are all going to be reverted
after execution anyway.  Also, this only applies to CAFs in compiled
code; CAFs in interpreted code are currently always retained.

Anyway, the old story is harder now that I removed the code that
checks whether a pointer is dynamically loaded or not (:-)).  Rather
than re-instate that code, I created a new version of newCAF
(newDynCAF), and arranged that the dynamic linker redirects any
references to newCAF to point to newDynCAF instead.  The result is
more efficient than before, and takes less code.

Include a static version of deRefStablePtr in case the code that uses
it was compiled without optimisation (and therefore doesn't get the
inlined version).

Make this compile again

Freshly generated by autoheader.

Using AC_CHECK_FUNCS rather than AC_CHECK_FUNC seems to allow
autoheader to pick up HAVE_LCHOWN.  Don't know why.

- remove unused CODE_BEFORE_DATA
- remove duplicate symbols
- kill extra whitespace
- add missing HAVE_FRAMEWORK_HASKELLSUPPORT and HAVE_IN_ADDR_T
