oops, back out local patch that accidentally got committed with rev. 1.139.

fix = vs. == in conditional

document the -recomp option explicitly.

'IPVARID :: type' moved from btype to type, to reduce conflicts.

Wibble.

(#ifdef incorrectly nested inside begin-end code)

Use createIOThread and not createGenThread, even for the interpreter.

Add simple mkWeakPtr/addFinalizer test.

The finalizer passed to mkWeak# might be NULL, so we'd better not
claim it's always pointer if we need to GC.  Another bug squashed...

*ahem*  Re-enable -fwarn-unused-binds and -fwarn-unused-imports...  :-}

Deprecations of variables now works, although the source location is
not yet reported correctly and the code needs some cleanup. Added a
new flag -fwarn-deprecations to the set of standard warnings. The
syntax of deprecations has been extended to deprecate types, classes,
or even constructors, although this does not work yet.

add -ltermcap when looking for -lreadline.

From: Michael Weber.

Nuke PTR_ON_HEAP and all associated ifdeffery; we always need it.

Make the desugarer a little more liberal about the class of case
expressions which get the special unboxed tuple treatment.

silence linker warnings on HP/UX.

From: Eric Schweitz <schweitz@nortelnetworks.com>

update for format changes in cacheprof.out.summary.

primUnpackString --> hugsprimUnpackString

Correct [un]blockAsyncExceptionszh_ret in the #ifndef REG_R1 case.

Don't always use GMP from ghc/rts; instead consult HaveLibGmp first.

Remove debugging junk accidentally left in :-(

Wibbles for Win32 standalone compilation of Hugs:
-- Turn off debugging miniinterpreter
-- Change SIZEOF_INTP (which no longer exists) into SIZEOF_VOID_P

Use the GMP library built in ghc/rts, not the system-supplied one,
since that doesn't exist on Cygwin.

#ifdef wurbles to aid Win32 compilation.

Handle `with' more cleverly.  I was generating partially applied methods
for the case where the `with' expression was also overloaded, but this
was buggy, and completely unnecessary.  Instead, simply force the method
binding at the point of the `with' expression (we reap no benefits from
pushing the sharing further out anyway), and release the remainder of
the method's context into the LIE.

Load deprecations from interface files into a deprecation environment
which maps Names to RenamedDeprecations. This map is not used yet, but
very soon it will...

This commit fixes a bug related to implicit parameters, too:
Previously, an interface file containing the name "with" could not be
read by the interface parser. This broke Malcolm's HaXml 0.9 (released
today). Remember Sven's glaexts-commandment (Jeffrey? :-) : Always
keep Lex.lhs's ghcExtensionKeywordsFM and ParseIface.y's var_fs
production in synch!

Space leak paranoia: Don't keep whole InterfaceDetails alive
throughout the middle part of the compiler

Ignore SIGPIPE, since our I/O library handles EPIPE properly and
SIGPIPE tends to cause the Haskell program to exit silently and
mysteriously.

Found-by: furiously pressing the refresh button in a browser connected
to my Haskell web server :-)

Extended interface mangler with deprecations handling.

NOTE: Whoever wrote this part of the driver without adding a HUGE
warning in MkIface.lhs to keep both files in synch deserves the most
severe punishment imaginable (huge stick, etc.)!  >:-(  The seemingly
magical random rearrangement of the interface file outside Haskell's
realm can drive you mad if you forget this...

Fixed typo in deprecations parsing

Write deprecations into interface files.

Get deprecation info out of the renamer again

Now deprecations can be read from interface files. To avoid a
lookahead of 2, the syntax for interface files has been liberated
slightly: They can end in as many freely mixed rule pragmas or
deprecation pragmas as you like.

Note: Parsing the deprecation pragma uses the same Lazy Technology (tm)
as the one for rules. Don't know if this makes sense, but it is
convenient here.

put SRTs in the text section.

Add copyright & Id

Module size wasn't taking into account the data section.

Fitst cut at XML-style profiling logs.  Time/allocation profiling only
for now, and the new flag '+RTS -px' enables the new log file format.

Result of my daily DEPRECATED-hour: Now it's possible to use the
pragma without harm, but nothing spectacular happens yet, only the
usual renamer checks (duplication, var in scope).

clean up: some parallel stuff had escaped from #ifdef PAR (Hans???)

sync with reality slightly.

Fixed pretty printing of DEPRECATED

Fixed pretty printing of RULES
