Refactoring for libgforth

use PER_THREAD

More consistent use of %p, sigaltstack is back

Don't use alternate signal stack (collides with multithreading)

Looping setjmp, use %p where appropriate

throw_jmp_buf only through a handler in the per-thread space

Better signal debug info

More debugging output in signal handler

Exception handling for threads

updated copyright years

android gforth works, changed recurse, fixed creating a binary distribution (not fully completed yet)

config file for android compilation

updated copyright notices for GPL v3

updated copyright years

Some bugfixes and cleanups by Jorge Acereda <AE069F38-47DD-4037-9434-89A9489456EF@gmail.com>

Added cygwin define

Work on Gforth NXT

C-based Gforth EC starts to work

updated copyright years

added checking for division by zero and division overflow to
  mixed-size division words (*/ */mod fm/mod sm/rem um/mod).
these exceptions are now tested in our test suite
fixed bug in testing

explicit checks for division by zero and overflow on division

added --ignore-async-signals
fixed typo

Modified some exported symbols to start with gforth_

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

bug workaround (cygwin signal blocking)
minor changes

Gforth now works properly when its stdout is to a broken pipe (but not stderr)
special SIGPIPE throw code (-2049)
minor bugfix ("uncaught exception" is now printed on stderr)

portability bugfixes
use SA_ONSTACK for all program-generated signals
updated README

portability changes
bugfixes in prims2x.fs, kernel/int.fs

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

Gforth now supports large files (>2GB) on small machines (32-bits/cell).
forth.h now asks for all kinds of POSIX, X/Open, and GNU support.
rearranged include files such that forth.h precedes the system files.

New file test/float.fs
FROUND-OFFSET now defined without f**
bugfix in signals (disabled SA_ONSTACK in most cases to allow graceful_exit).

FROUND is now implemented in high-level Forth.
  The primitive is now called "(FROUND)".

work around missing MacOS X FPE_... si_codes

Gforth now survives destruction of the C stack pointer (it now uses
  sigaltstack() to set up signal handling on another stack).

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

Thrown out static vocabulary stack
Changed cross to make mixed threading workable

Fix for terminals where TIOCGWINSZ doesn't work
Added bindkey to history.fs

changed FSF address in copyright messages

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

updated BUGS

fixed typo

signal portability improved

fixed another signal bug

signal handling bugfix (not yet portability tested)

Made USE_TOS work with 386 on gcc 2.95

On platforms that support the SA_SIGINFO flag (Linux is not quite
  there yet), there are now new signal handlers that perform more
  precise error reporting (in particular for SIGFPE and SIGSEGV).
Minor fixes.

started working on better signal handlers

moved signal handling into a new file signals.c
minor changes to window size handling
