Fix a number of bugs in the autoconf setup, thanks to Gregory Wright

remove a vestige of the long-gone FLOATS_AS_DOUBLES

import of hscThing needs to be conditional on GHCi status.

Re-adding the -i flag for heap profiling.

The problem was that profiling forces 2-space collection,
and the census was done on *every* GC. Now, we still keep
the 2-space for profiling, but just do the census periodically,
according to a new flag, -i<secs>.

Restrict ghc-4.xx breakage to mingw only; not an issue for other plats

Add support for Hugs's :info command. Doesn't work yet, but shouldn't
interfere with anything else. Some of the files touched are just to correct
out-of-date comments.

Highlights are:

hscThing: like hscStmt, but just gets info about a single identifier
cmInfoThing: exposes hscThing's functionality to the outside world

Fix typo (variable name wrong; wouldn't build)

wibble - the joys of CVS conflict merging

Include way in HSC_C_OBJS to clean *_hsc.p_o too.

Drop the dependency on the Win32 library, as it is only used in an
extremely limited way (a single 'foreign import' is all that's reqd)
[Sorry Reuben, I don't buy your 'extra deps are good' argument :-) ]

runSomething: narrow down prev commit, only quote args under mingw;it interacts badly with -D quoting already done on other plats (and isn't reqd)

Add comment and use backslash consistently

--------------------------------
	First cut at the demand analyser
	--------------------------------

This demand analyser is intended to replace the strictness/absence
analyser, and the CPR analyser.

This commit adds it to the compiler, but in an entirely non-invasive
way.

	If you build the compiler without -DDEBUG,
	you won't get it at all.

	If you build the compiler with -DDEBUG,
	you'll get the demand analyser, but the existing
	strictness analyser etc are still there.  All the
	demand analyser does is to compare its output with
	the existing stuff and report differences.

There's no cross-module stuff for demand info yet.

The strictness/demand info is put the IdInfo as
	newStrictnessInfo
	newDemandInfo

Eventually we'll remove the old ones.

Reset the terminal on exit so that ghci doesn't leave it messed up. To see
what I mean, run ghci, then type :q RET, then su return, and start typing a
password. Alarming, isn't it?

This fix needs a patch to the Readline library (next commit).

Make -u's and symbols into separate args

1. Make GHC work with paths and filenames containing spaces (hopefully).
This is done by quoting all arguments sent to the shell. To avoid causing
problems, this means that each argument in a list had *better* be a single
argument, hence the next commit to PackageSrc.hs.

2. undosify the path passed as the -h argument to unlit, to make unlit work
on Windows again.

3. Fix getExecDir for Windows (broken by previous changes to the meaning of
-B).

Typos in a comment. Whitespace at eols.

Fix comment.

Long long functions are no longer in the rts.

Follow the s/includes/include/ change in package.conf.

Add ghc-usage.txt to install tree info

GHC_INCLUDES => GHC_INCLUDE_DIR

Modify Windows installation instructions in accordance with the Way Of
The Future.

Fix markup bugs; add documentation about deprecations

Add docs re installed file layout

Remove spurious space.

Don't add -I flag for Windows gcc's include files here; do it in
package.conf instead.

Add C includes path for Windows here rather than hardwiring into
SysTools.lhs. Change to include rather than includes.

Now assume that -B passes libdir, not libexecdir

Binaries now live in extra-bin

Fix binary finding for Unix

Tidy up Type/TcType stuff in DsCCall/DsForeign

Set -DDLLized when DLLized is true for use in C source

Add stubs for ILXized cbits DLL.

Don't call resetNonBlockingFd when DLLized; this stops the cbits DLL
depending on the RTS, which ILX needs; it doesn't matter for Windows, as
that doesn't have non-blocking IO implemented anyway.

Fix DLL building, and add support for linking .hsc.o files into cbits libraries

s/extra-bin/bin/ because this is where all programs are installed to.
Perhaps it should be changed the other way around - I don't know what
this extra-bin was supposed to be.
