add takeMaybeMVar#

hack to fix bootstrapping

Add takeMaybeMVarzh  (I'm doing this commit in bits, since my working
sources are so full of changes I can't easily unpick them...)

Cleaned up Addr, AddrOff added

Add -fcompiling-prelude so as to get right dependencies in the interface.

Cygwin wibbles.

More infotable cleanups: zap the debugging table of info table names.
This can be cleanly done by looking at the .itbl field on Names and Tycons.

checkClosureShallow: allow Hugs constructor itbls

Cleaning up the foreign object naming mess:

   * Renamed the primop from makeForeignObj# to mkForeignObj#, this
     is more consistent with the old Foreign.mkForeignObj.

   * PrelForeign now exports makeForeignObj with the new signature.

   * freeFile.c now uses StgAddr instead of StgForeignObj, this
     removes the need for some fixIOs.

   * Lots of import tweaking to prepare The Big Foreign Renamer,
     which will move most of Foreign to ForeignObj, and FFI to Foreign.

Note: I've tried to track the changes in the interpreter sources, but
didn't test them.

Pull init_stack outside #ifdef INTERPRETER.

Fix bitrot to allow (standalone) StgHugs to be built on Solaris, so we
can Purify it.

Ensure that when Hugs decides to unload a module (nukeModule()), there are
no closures anywhere in the system which refers to infotables defined
in that module.  That means reverting all CAFs and doing a major GC
prior to deleting the module.  A flag is used to avoid redundant GCs.

Render formatting consistent with the Glasgow Style (vapour-)Guide.

remove syslib misc.

not the dmgob_ guys; we don't have the Native library anymore.

syslib wibble

don't try to recurse into non-directories.

Use STArray instead of MutableArray.

update expected output.

oops, this output is bogus.

Update for Haskell 1.4 (!!!) and update expected output.

String isn't a valid _ccall_ argument type anymore.

Add io subdir

Wibble

Add nested hPutStr/tracing test

When building way=u, merge cbits/*.o into ./libHS_cbits.u_o, for Hugs.

Make it so that -fcompiling-prelude applies only
for Prelude modules (i.e. ones called Prelxxx).

I've done this with an {-# OPTIONS #-} line in each
such module (they all has -fno-implicit-prelude anyway)
but a less repetitive approach in the Makefile would
be welcome.

Load the compiled Prelude directly from its build location, ghc/lib/std.

Update EXTERN_SYMS_linux/EXTERN_SYMS_ALLPLATFORMS to fix Win32 build.

Make getArgs and getProgName behave identically in combined and standalone
modes.
