updated copyright years

support for assembler definitions with host platform's ABI calling conventions
('ABI-CODE')

updated copyright years

The Makefile now uses an EMACS variable
Eliminated most compilation warnings

updated copyright notices for GPL v3

updated copyright years

GCC_PR15242_WORKAROUND is now a configure variable, not an option
default is now to use the workaround for gcc-3.x, but not for other gccs

updated the copyright year on many files
added FSF copyright header to complex.fs fft.fs regexp-test.fs regexp.fs
added fsl-util.fs to update-copyright-blacklist

threw out THREADING_SCHEME, now Scheme 8 is used everywhere.

EXECUTE and friends are now relocatable again even with the PR15242 workaround.

preparations to make EXEC relocatable with PR 15242 workaround

bugfix
Bench result added

Fixed problems with workaround

added configure option --disable-gcc-pr15242-workaround
bugfixes for the gcc pr15242 workaround

preparation for gcc PR 15242 workaround
minor changes

updated copyright years for files changed in 2004

Changed empty expressions to do { exp } while(0)

activated gforth-native again
some gforth-native bugfixes and changes

now an is-branch? field is generated engine/costs.i
fixed some typos in README
changed default threading scheme for generic machine

Defined run-time routines (docol etc.) as primitives, eliminated some
  special-casing and "+DOESJUMP+1" etc. in engine.c and main.c
Defined the enum type PrimNum and replaced many shorts with PrimNums
  (gives nicer gdb output)
Workaround for the absence of the FPE_... macros in FreeBSD/Alpha 4_STABLE

updated copyright years

changes to eliminate gcc warnings

PPC fixes and speedups

Fixed look problem
Added benchmarking of all engines

First inclusion of group-based primitive tokens (no reordering happend yet)

cfa is now killed in NEXT_P2 in some direct threading schemes (for better
  register allocation)

new engine gforth-native (works on 386 arch only for now).
  appropriate changes in control-flow instructions in prim
  new primitives SET-NEXT-CODE and CALL2 (not necessary for the other engines)
  new primitives COMPILE-PRIM1 and FINISH-CODE
  prims2x.fs now produces IMMARG(...) macros for initializing immediate args
  prims2x.fs: changes in some of the output-c-tail words (goes with the
     changes in the control-flow words).
  appropriate changes in engine.c
  engine.c: rewrite of check_prims, support for gforth-native (NO_IP)
  threaded.c: support for NO_IP
  various kernel files: started to eliminate return stack manipulations for
    embedding data (e.g. string literals); incomplete.
dynamic superinstructions now use LABEL2 instead of IS_NEXT_JUMP
FORCE_REG has no effect if DOUBLY_INDIRECT (gcc-2.95.1 crashes otherwise;
   it's unclear which change provoked this).

hybrid direct/indirect threading (replaces direct threading)

bugfixes

Differentiate between threaded code and xts in gforth-ditc and in gforthmi

use LABEL(name) instead of CASE I_name at the start of a primitive
fixed read-line tutorial documentation bug

prims2x now generates CASE before the label

bugfix

finishing touches to dealing with inst-stream in prims2x.fs
converted prims to using this new feature for inline arguments (prefix '#')
commented out prim* targets in engine/Makefile.in (out-of-date)

Simplified threading scheme for PPC (faster with gcc-2.95 on 604e and G4).
Commented out hilight stuff in gforth.el (turned on hilighting everywhere).
Fixed wrong use of add-hook, and replaced use of (obsolete)
   comment-indent-hook with comment-indent-function.

changed FSF address in copyright messages

updated copyright dates in many files (not in ec-related files)

documentation changes

CFA_NEXT is now defined by the threading scheme and not when GETCFA is
missing. With Gforth-debug we might have GETCFA defined and a threading
with cfa alive.
With this fix I managed to compile gforth on a system that claims it is
a 386 (i386-solaris, BTW: it is a PII...). But gforth crashes
(direct threaded scheme 10) at the moment.
Perhaps Anton should take a look on it?!

cleaned up threading stuff:
  now the schemes are selected with -DTHREADED_SCHEME=n
  there is now a macro SET_IP for setting ip.
New threading schemes: for Power (20% speedup on 604e) and a plain scheme

updated dates in copyright messages
inserted copyright messages in most files that did not have them
removed outdated files engine/32bit.h engine/strsig.c

jwilke's changes:
Moved many files to other directories
renamed many files
other changes unknown to me.
