autoconf hackery for CTypes{,ISO}

Remove out-of-date table that conflicts with the new one in the FFI
documentation.

Commented out the revision history.

Improved link to Foreign hslibs stuff.

Tidied up a table.

Better chapter name.

Added new FFI story from fptools/docs, and removed ccall docs.

Pls mrg

Make object file splitting simpler, in preparation for conversion to
the new driver.

The "inject split markers" phase is now omitted, instead we generate
the split markers directly.

Driver: also removed now-defunct -fpedantic-bottoms flag.

Changed ffi doc to worker-wrapper format.

remove unneeded file.

update interface file syntax

update expected output

Move read010 to rename/should_fail; this is really a renamer test.

DocBooked and moved here from hdirect/doc.

Fix printing of unfoldings in hi-files: lambda binders are now grouped
again like they used to be, rather than printed one-at-a-time.

Adding types to the names inside the GOO.

All needed for a langauge with unboxed types ...

More wibbles towards compiling data constructors and unboxing correctly.

Significant reworking of Java code generator, towards
getting unboxing working.

The n-th attempt to get GCD right, this time negative Int arguments in
combination with zero. Another bug in this area and I'll leap out of
the window immediately...  :-P

Synched with reality

Added tests for gcdInt/gcdInteger

Fixed braino.

The GCD saga continues: Fixed gcdInt/gcdInteger to work correctly for
non-positive values, i.e. call mpn_gcd_1 only with positive inputs,
and issue an error if both operands are zero. This should fix the bug
reported by Marc.

Unbreak the driver again

Class decls weren't taking functional dependencies into account when
checking for ambiguous type vars.  Fixed.

Updated DocBook notes to reflect heroic efforts of Messrs Panne and
Chakravarty.

Added new greencard package.

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".

update expected output.

update expected output

Update expected output.

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