checkTyCon shouldn't look through newtypes.  Instead, we add a new
function checkRepTyCon which does, and use it in the few cases where
it is needed.

This fixes a nasty bug with overloaded literals of newtypes, and
probably a whole bunch of other lurking bugs too.

add new flag -fglasgow-exts-no-lang, which is the same as
-fglsagow-exts but doesn't include the implicit -package lang.  This
is needed only for compiling ghc/lib/std, where hslibs/lang may or may
not exist.

Fix bug in new version of hGetLine: it didn't handle unbuffered
handles properly.

The fix involves re-importing the old code for hGetLine :-(

While adding a syslib, setup include dirs in addition to cc injects, too.
The driver is really a piece from hell... :-(

The DocBook saga continues: Look for already installed catalog first.

allow infix constructors to be declared with prefix notation, eg

	data T a b = (:^:) a b

Test for declaring an infix constructor using prefix notation, eg.

	data T a b = (:^:) a b

Compile FastString with -fvia-C for the time being (Julian is working
on fixing a bug in the NCG).

fix apparent cut-n-pasto: rEC_SEL_ERROR_ID was printed as "patError".

Incorporate Josef's patch to fix the bogus warning about overlapping
string patterns.  Thanks Josef!

Always run docbook scripts with the catalog as the first argument (taken
from DOCBOOK_CATALOG).

Update to use DOCBOOK_CATALOG to get the correct catalog.

Use new way of #including for packages

floatExtreme.h's definitions reside in PrimOps.h

Trying to get the whole #include business right: ccalls are unfolded
into interface files, even without -funfold-casms-in-hi-file. Although
this is a good thing performance-wise, the header files should better
be #included during compilation of the .hc files. Solution:

   * Every .hc file #includes "Stg.h" first.

   * For every package `foo' used, "HsFoo.h" is #included, too. This
     means that every package has to come with a corresponding header
     file, even if it is empty.

Downside:

   * Getting #includes right with ghc-inplace is a little bit ugly:
     The boot target in Makefiles must copy the package's header files
     into GHC_INCLUDE_DIR (don't forget the clean target!), and final
     installation of those headers is done there, too.   :-P  Better
     solutions are highly welcome.

   * Possible pollution of the C name spaces.

Cleanup pass on functional dependencies.  Most noticeably, make it so that
signatures involving classes with functional dependencies work.  Also,
Fundeps are now properly handled by the simplifier, resolving problems
where the fundeps were sometimes being discarded too early, and sometimes
hanging around too long.  Took out the early ambiguity testing in the
renamer, because that's too early (you don't know the fundeps yet).  Now,
the ambiguity test happens in the typechecker.
Functional Dependencies should now be up to snuff with Mark's paper,
however, the derived instances and superclass extensions found in hugs
are still not in there.
It would be nice if this were merged into 4.07.  I have diffs against
the 4.07 tree in case it's too thorny working around Simon's big commit.

Autoconf magic to determine a working DocBook CATALOG file (if any).  Makes
the makefile variable DOCBOOK_CATALOG refer to this CATALOG file (absolute
path).

Nothing uses this file, so remove it.

don't need to import PrelPack.hi-boot

only add implicit occs for bindIO & returnIO for foreign export, not
for foreign import.

Fix package names & version numbers in .hi-boot files.

Fix cyclic dependency problem when compiling the Prelude.

re-enable first float-outwards pass; it was accidentally disabled in
Simon's recent commit.

Fix missing imports for foreign import/export

Hopefully this is a better place to fix the printing of litlits in
interface files...
*please merge*

Backed out previous commit, the change was at the completely wrong place.
*please merge*

Don't forget litlit alternatives when deciding if an expression should
make its way into an interface file.
*please merge*

Prefix litlits with "__litlit" in interface files.
*please merge*

Look through newtypes when generating stub code.
*merge if/when SPJ's huge commit is merged*

Removed unused import.

Rewrote RULES for gcd and lcm without forall. The old versions *did
not* always fire because of a strange interaction with automatically
generated specialisations for gcd! Example for this misbehaviour:

   main :: IO ()
   main = do
      print (gcd             15675            156750 :: Integer)
      print (gcd 12345678987651075            156750 :: Integer)
      print (gcd            156750 12345678987651075 :: Integer)
      print (gcd  2469135797530215 12345678987651075 :: Integer)

I don't understand why the new version works and the old one did not,
so somebody else should probably have a look at this phenomenon.

*please merge* (like all my commits in the last few days :-}

Added a few -#includes to eliminate warnings from gcc
(*please merge*)

Fixed gcdIntegerInt# primop, the previous macros was completely
wrong. gcd for Integers worked only as long the corresponding RULE
in PrelReal didn't fire.

The C functions toLocalTime and toUTCTime now return an StgInt, not a
rather useless StgAddr. This fixes two gcc warnings during the
compilation of Time. In the course of this, toLocalTime.c and
toUTCTime.c are synched a little bit more.

(*please merge*)

Lowered magical value of unfolding threshold for PrimPacked, so strlen
doesn't appear in interface file. This fixes bootstrapping problems,
e.g. when compiling FastString. Extremely hacky solution...

Bug or feature? Changed `envyron' back to `environ', otherwise
hslibs/posix/cbits/env.c can't be compiled. If this breaks something
on M$, it must be #ifdef-ed somehow, but not simply be renamed.

Applied patch from hugs98 fixing type annotations in do bindings.
