When -DDEBUG, in BYTE_ARR_CTS, allow GET_INFO(a) to be
&MUT_ARR_WORDS_info as well as &ARR_WORDS_info.

- check failed_to_evac in scavenge_static.  We might have a static
  indirection (i.e. a CAF) that we can't evacuate to the oldest generation,
  so we have to put it back on the old generation mutable list.

With this change, a bootstrapped compiler now compiles the libraries
successfully.

- Don't forget to set failed_to_evac when evacuating a THUNK_SELECTOR
- Fix GC counting

Changed expected output to reflect new reality.

Added a generational garbage collector.

The collector is reliable but fairly untuned as yet.  It works with an
arbitrary number of generations: use +RTS -G<gens> to change the
number of generations used (default 2).

Stats: +RTS -Sstderr is quite useful, but to really see what's going
on compile the RTS with -DDEBUG and use +RTS -D32.

ARR_PTRS removed - it wasn't used anywhere.

Sanity checking improved:
	- free blocks are now spammed when sanity checking is turned on
	- a check for leaking blocks is performed after each GC.

Code generated by implementTagToCon() gives a useful error message
in case of invalid arguments.

testing

Z-encodings for '/' and '.' were both 'Zd'.  Change '.' to 'Zs'.

Added check target.

Made FILE_OBJECT be defined for -D__HUGS__.
Changed .dll file refs to .so for -D__HUGS__.

Created a Makefile for fptools/ghc/interpreter.

Disabled nonblocking IO (the +128 for file flags) until missing prims
are implemented.

Removed extraneous test following 'if ( fo->flags & FILEOBJ_NONBLOCKING_IO )'

Fixed caching bug in FPTOOLS_END_{TEXT,DATA}_SECTION.

Added new option -f, which forces the creation of 'todir' if it doesn't
already exist.

Added definition of WithGhcHcVersion (but left commented out, as it's currently
unused.)

mkdependHS: for "source" imports of the form, e.g.,

   import {-# SOURCE #-} Foo

emit dependency on Foo.hi-boot-<iface-file-version-number>
rather than just Foo.hi-boot if the former exists.

Generate static closures with float/double fields properly.

Fix endianness problems in info table generation.

Added -fno-asm-mangling.

Add missing <p>

Doc changes for revised exception interface.

Add missing export of warnPprTrace (for WARN macro).

Fix RnEnv.mkPrintUnqualFn

Revised interface to the exception library.  Docs to follow.

this file is NON_POSIX_SOURCE, since we use lstat.

#include <unistd.h> to get prototype for vfork.

Add missing pattern to tidyNote.

Small changes to make the compiler boot itself

Add debug macro WARN

New rev5 hi-boot file.

Sync up with .hi-boot file.

Sort unboxed slots - part of the fix for large bitmaps.

Fixes to the large bitmap code.

Oops; committed wrong version.  Revert previous commit.

Fixes to the large bitmap code.

- check for silly stack sizes in the right place
- stub the link field of the running TSO (fixes a bug in the
  _ccall_GC support).
