Adding type signature to main.

To workaround gcc/egcs bugs re: handling of non-toplevel "extern" decls,
lift them out to the top. i.e., extend mechanism by which "typedefs"
are lifted out to the toplevel (for the same reasons) to also encompass
"extern"s.

Note: the default is not to emit an "extern" decl for every _ccall_,
as this runs the chance of (trivially) conflicting with header file
includes. So, to enable, use -optC-femit-extern-decls.

#include wibble

portability wibble

Minor efficiency improvements to Prelude I/O functions.

Pure Win32 builds doesn't support non-blocking IO

wibble

attach version info

s/TargetPlatform/TARGETPLATFORM/g

Support for baking version info into the gen'ed Prelude DLL

cbits/ is now also built in a DLL way, if needs be.

INSTALL_* tweaks

Make foreign import and thus the Prelude work on cygwin.

Basic #ifdeffery to make StgHugs compile out of the box on cygwin.

Adding in the modified versions of the Standard Haskell 98 libraries.
These should compile under both Hugs and GHC.

use the flags  -D__HUGS__ -DUSE_REPORT_PRELUDE to extract the Hugs src.

Fixing bug with derived Read/Show of labeled fields.
(showField and readField were undefined).

Wibble in printing of type contexts.

When generating C stubs, honour -osuf <x> option

More {-# OPTIONS .. #-} tweaks: handle -#include "..." (where
'handle' == 'ignore'.)

Make platform-specific dynamic loaders add ".so", ".dll" etc to
library names, so that f-i decls can be written without them.
Modify Prelude accordingly.

Remove unused functionality in dynamic.c and make err msgs a bit
better.

Don't warn user of unrecognised options when processing
{-# OPTIONS .. #-} pragmas.

More RULES documentation

Use C-style comments instead of assembler comments - the '#' confuses
cpp when mkdependC'ing.

Support for "{-# OPTIONS <opts> #-}" in headers of (de-litted)
source files. Currently, only -syslib <foo> and "-fglasgow-exts"
settings are picked up from within <opts>.

Mildly tested; give it a twirl.

remove debug printing -- wibble

Dot-ify local labels.

universal_call_c_x86_stdcall: assume *I* have been ccall'd, not
stdcall'd, so don't clear my own args on return.

reduce block size to 4k

small cleanup; reduce amount of conditionally-compiled stuff

Add way 's', for SMP/PThreads

Junk removal

Fix crashes in re_search.  Several other functions in this file need
fixing too.

Add foreign import/export implementations for x86 stdcall convention.

Make parser notice calling conventions on f-i and f-x declarations,
check they are supported on the platform Hugs is compiled on.  Pass
them all the way through the code generator to the interpreter.

Allow f-i/f-x decls to omit the calling convention, in which case
ccall is used.  Remove calling convention from all such decls
in the Prelude so it will work on any platform.

markStablePtrTable: correctly handle case when one stable ptr refers
to an indirection to an item referred to directly by a second
stable ptr (I think!).

wibble

Foreign imports that use ByteArrays now need to be marked as being 'unsafe.'

Fix documentation installing in a binary dist.

FFI wibble:

* disallow the use of {Mutable}ByteArrays in 'safe' foreign imports.
* ensure that ForeignObjs live across a _ccall_GC_.

Adding a axiomatic testing framework library to help test Hugs and GHC
libraries.

Here is the example for the test of concat.

test_concat = testRules "concat" [
	do (xss :: [[ALPHA]]) <- var "xss"
	   concat xss <==> foldr (++) [] xss
	]

xss here ranges over various rendering of list of list,
including bottom and lists containing bottom.

<==> uses a small piece of compiler/interpreter specifics to
allow testing for

	error "" ... <==> ... error "" ===> Pass

* Completion of foreign import and foreign export for x86 ccall
  convention.  f-i's and f-x's can pass and return
  Char Int Word Addr StablePtr Float and Double.

* Significant cleanups and infrastructure improvements.
  Characterise functions by (instruction set, calling convention)
  pair where necessary, since that's what counts.

  Moved foreign export code into rts/ForeignCall.c.
  Should now be in a good position to implement x86 stdcall
  convention.
