- ANSIfy
- add a couple of comments about dodgy-looking code

ANSIfy

- context switch after a `par`
- remove some #if 0'd code

non-functional changes that were sitting in my tree.

update a couple of things.

Don't attempt to split objects built from _stub files.

Patch from Michael Weber <michael.weber@post.rwth-aachen.de>.

Remove StLitLit, and clean up somewhat the handling of
stdout/stderr/stdin in CLitLits (in StixPrim.amodeToStix).

Put a giant loop around awaitEvent, to protect against
awaitEvent(rtsTrue) returning with no threads to run.

This can happen if we try to delay for some time X, and select(2)
decides to wait for a shorter time X-\delta instead.  It appears that
Solaris is more prone to doing this than Linux.

This fixes the "schedule: invalid whatNext field" crashes that people
may have seen.

Zap a couple of trace-s.

Change alignment directives for x86 segment changes to something
more plausible-looking for Linux.

genCodeInfoTable, genBitmapInfoTable: construct type_info to reflect
non-presence of flags in type info field.

Added how-to for GHC's use of DocBook. Just describes a few conventions for
particular tags at the moment.

Seeking didn't take into account the size of the current buffer
(although it seems the intention was there: the proper offset was
calculated, just never used).

This fixes the io013 failure.

StixPrim.amodeToStix case CMacroExpr: handle UPD_FRAME_UPDATEE
StixMacro.macroCode: handle UPDATE_SU_FROM_UPD_FRAME

Print a couple of blank lines in final assembly output in between basic
blocks, to make it easier to match up with the output of -ddump-stix.

macroCode: implement PUSH_SEQ_FRAME

SPJ's Windows installation notes added in.

New building guide with Windows notes added and binary installation notes
removed.

New version of installing.sgml produced; old literal system no longer used.

- add missing FB_ macro
- correct a couple of comments

Added binary installation chapter to user guide, made from old installation
guide and Sigbj?rn Finne's Windows installation page.

checkCode: handle HP_CHK_UT_ALT.

Move closure type printing stuff to Printer.c, since it's generally useful.

cleanup, remove some bogus-looking stuff from DEBUG code.

primCode: implement DataToTagOp.

Minor cleanup (to get rid of warnings)

cleanup

eliminate warning.

Add proper SMP locking to blackhole entry code.

Minor cleanup to get rid of warnings.

expose 'par' now that we have an implementation for both sequential
and SMP ways.

Bugfix (raiseError in non-enterable closures); added GranSim code to Schedule.c

- remove duplicate GHC_SYSMAN_DIR
- remove unused GHC_HSP_DIR

stmt2Instrs: correctly handle StData with zero data words

genCodeInfoTable: don't do getSRTInfo on the closure info if we already
know via infoTblNeedsSRT that an SRT isn't needed.

gentopcode: handle CClosureTbl.

Merged GUM-4-04 branch into the main trunk. In particular merged GUM and
SMP code. Most of the GranSim code in GUM-4-04 still has to be carried over.

Rearrange top-level nativeGen plumbing so that -ddump-stix is visible
even if subsequent nativeGen passes crash.

Added a rudimentary implementation of -ddump-stix.

- remove AllBlocked scheduler return code.  Nobody owned up to having
  created it or even knowing what it was there for.

- clean up fatal error condition handling somewhat.  The process
  exit code from a GHC program now indicates the kind of failure
  for certain kinds of exit:

	general internal RTS error	254
	program deadlocked		253
	program interrupted (ctrl-C)	252
	heap overflow			251
	main thread killed		250

  and we leave exit codes 1-199 for the user (as is traditional at MS,
  200-249 are reserved for future expansion, and may contain
  undocumented extensions :-)
