updated copyright year

Sincos clobber problem fixed by using sincos()

Clobber workaround checked on Windows

Tests and workaround for the bug (of glibc) that functions like fsin
   clobber TOS on 386

moved TOS to %ecx to avoid fsin etc. bug

Best effort for Mac OS X 32 bit with gcc-4.2

updated copyright years
updated copyright-blacklist (added libltdl)
updated distributed files (don't distribute files without distribution terms)
added copyright to preforth.in and build-ec.in

Fix a few building bugs

updated copyright notices for GPL v3

updated copyright years

generalized code padding and added 386 and AMD64 padding

Found register combination for gcc 4.2.0

make --enable-force-reg work with gcc-4.1

updated copyright years

Simplified FM/MOD SM/REM UM/MOD to use fmdiv or 5-argument ASM_...
Eliminated 4-argument ASM_...

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

documented 2 bugs
minor bugfixes and cleanups

threw out THREADING_SCHEME, now Scheme 8 is used everywhere.

added M/MOD asm support for 386 and AMD64 with FORCE_LL

updated copyright years for files changed in 2004

minore bugfixes (Makefile.in)
enabled 3-state stack caching for gforth-fast and gforth-native
   bugfixes (EXECUTE and PERFORM; spbREG use)
   explicit register allocation to spb for gforth-native, but not gforth-fast
   Due to the shortest-path algorithm this means that gforth-fast uses only
     S0 and S1, not S2, so we could keep that.
     However, we probably want to use more states etc. for other
     architectures, so we may want to have a way to select different
       cache.vmg and different peeprules.vmg files for different
       archs, builds, and binaries.

gforth-prof is built by default again
default CFLAGS is now "-O2" instead of "-g -O2"
added some static superinstructions
fixed computation of engine/costs.i
minor changes

updated copyright years

undid changes to copyright notices

Updated copyright notices
Added stack effects to kernel/input.fs

Some changes for portability to AIX and Darwin
Eliminated the (non-hybrid) direct threading stuff from arch/*/machine.h

minimized differences between engine and engine2 to avoid register
  allocation differences
disabled USE_TOS on 386 without FORCE_REG (otherwise sp is spilled)

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).

gforth now stores a local ip to saved_ip instead of using a global ip
  associated changes in register allocation, threading, documentation
testdist now also tests vmgen and vmgen-ex

cleaned up #defines of DIRECT_THREADED and INDIRECT_THREADED
introduced engine gforth-itc (indirect threading, no replication)
fixed bug in indirect threading

hybrid direct/indirect threading (replaces direct threading)

default dictionary size 1M cells
machine-specific stuff for dynamic superinstructions is now in machine.h
support for dynamic superinstructions for Alpha

more register allocation fine-tuning; USE_TOS is again used with gcc-3.*

explicit register allocation for gcc-3.0.x (not as good as gcc-2.95, but
  better than before); don't use TOS with gcc-3.x, so rp can be allocated.
Compile engine.c with -fno-gcse (to improve gcc-3.x code quality).

changed FSF address in copyright messages

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

added primitives utime cputime v* faxpy
changed default on 386 to USE_NO_FTOS

SEE now guesses the length of primitives and code words
It now also works for code words in  direct threading
CODE_ADDRESS now works for direct threaded primitives
    on 386 and (hopefully) PPC

Some small further changes for fast USE_TOS with gcc 2.95

Made USE_TOS work with 386 on gcc 2.95

bugfix in m68k/machine.h and 386/machine.h
doc changes in cross.fs and prim

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

Several fixes and typos I forgot to check in until recently
Documentation additions (not completed)

Dos Changes:
!!Moved:
engine/32bit.h moved to arch/generic/machine.h
cache.c moved to arch/hppa/
cleanalign.c moved to engine/
!!New Files:
envos.* *.bsh
Instead of linking arch/xy/machine.h an custom include path is used
engine.a engine.o main.o makes with engine/Makefile now
history.fs and startup.fs works for dos and unix now
environment variable osclass is set in envos.fs, wich is os-specific
any comments?
supressed some warnings in main.c

Some bug fixes.

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