remove ghc/docs/libraries from the bindist, add hslibs/doc

trivialCode (x86), when fst arg is immediate, assumed you could reverse
the order of operands, but not true for eg subtract.  Fixed.

Make this test more comprehensive.  We now test

	+,-,div,mod,quot,rem,gcd,lcm

over a range of legal operands, for both Int and Integer.

- add some more test cases, now shows up the minInt bugs in Integer
division.

The minInt saga continues:

 - fix several Integer division-type functions for the
   case when the dividend == S# (-2147483648#).

amodeToStix: correctly compute offset for CHARLIKE_closure-s.

Add comment about code generation for debug tracing.

MachCode.stmt2Instrs, StFunBegin, x86 case only: for debugging,
generate trace code to print the name of each labelled code block.

genCCall for x86 assumed that all args were 4 bytes long :-(.
Now works with doubles too.

Remove `libraries' from SUBDIRS

Remove old libraries documentation.

sync up output

syslib fix

Don't spew floating/double literals into assembly output, since this
causes difficulties with FP numbers near the edges of the allowed
ranges.  Instead, convert them to a sequence of bytes and emit those.

syslib fixes.

remove -syslib misc.

fix a few -syslib options.

Don't hold the lock on the Handle while we block waiting for data on a
read.  This is a partial solution to the general problem of holding a
lock on the Handle while in mayBlock.

- 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.
