   User-visible changes between 0.6.2 and 0.6.9 (up to 2008-07-16):
   
   Requirements:
     At run-time requires libtool and gcc (for libcc C interface) and
                          gdb (for disassembler (SEE) on some platforms).
   Installation:
     support for DESTDIR, POST_INSTALL, INSTALL_SCRIPT
     automatic performance tuning on building (--enable-force-reg unnecessary)
     report performance and functionality problems at end of "make"
     autogen.sh now exists
   License:
     Changed to GPLv3
   Bug fixes
     Now works with address-space randomization.
     The single-step debugger works again in some engines.
     Many others.
   Ports:
     AMD64, ARM, IA-64 (Itanium): better performance
     PPC: disassembler and assembler (32-bit)
     Gforth EC: R8C, Lego NXT (not distributed; complete?)
     MacOS X: better support
   Invocation:
     New flags --ignore-async-signals, --vm-commit (default overcommit)
               --print-sequences
   Forth 200x:
     extension queries (produce true for all implemented extensions)
     REQUIRED etc. (not new)
     [DEFINED] and [UNDEFINED]
     PARSE-NAME (new name)
     deferred words (new: DEFER@ DEFER! ACTION-OF)
     X:structures: +FIELD FIELD: FFIELD: CFIELD: etc.
     X:ekeys: new: EKEY>FKEY K-SHIFT-MASK K-CTRL-MASK K-ALT-MASK K-F1...K-F12
   Unicode support (currently supports only uniform encoding):
     added xchars words for dealing with variable-width multi-byte characters
     provide 8bit (ISO Latin 1) and UTF-8 support for xchars
   Number prefixes:
     0x is a hex prefix: 0xff and 0XfF now produces (decimal) 255
     # is a decimal prefix: #10 now produces (decimal) 10
     Signs after the number prefix are now accepted, e.g, #-50.
     ' now only handles a single (x)char: 'ab is no longer accepted, 
                                          'a' now produces (decimal) 97
   New words:
     \C C-FUNCTION C-LIBRARY END-C-LIBRARY C-LIBRARY-NAME (libcc C interface)
     LIB-ERROR (complements OPEN-LIB)
     OUTFILE-EXECUTE INFILE-EXECUTE BASE-EXECUTE (limited change of global state)
     16-bit and 32-bit memory acces: UW@ UL@ SW@ SL@ W! L! W@ L@ /W /L
     NEXT-ARG SHIFT-ARGS (OS command-line argument processing)
     NOTHROW (for backtrace control)
     FTRUNC FMOD (undocumented)
     SEE-CODE SEE-CODE-RANGE (show generated dynamic native code)
   Improvements/changes of existing words:
     S\", .\" now support \l, \m, \z, and limits hex and octal character specs.
     OPEN-FILE with W/O no longer creates or truncates files (no compat. file)
     OPEN-LIB now understands ~ at the start, like OPEN-FILE.
     TRY...ENDTRY changed significantly, compatibility files available (see docs).
     The disassembler (DISCODE) can now use gdb to disassemble code
     Uninitialized defered words now give a warning when executed
     Division is floored (disable with "configure --enable-force-cdiv")
     Gforth (not gforth-fast) reports division by zero and overflow on division
       on all platforms.
   Newly documented words:
     S>NUMBER? S>UNUMBER?
     EKEY keypress names: K-LEFT  K-RIGHT K-UP K-DOWN K-HOME K-END K-PRIOR
       K-NEXT K-INSERT K-DELETE
     CLEARSTACKS
     FORM
   Environment variable GFORTHSYSTEMPREFIX (used by word SYSTEM and friends)
   C interface:
     exported symbols now start with "gforth_" (for referencing them from C code)
     libcc C function call interface (requires libtool and gcc at run-time)
       alternative: undocumented libffi-based interface
   Libraries:
     depth-changes.fs: report stack depth changes during interpretation
     ans-report.fs now reports CfV extensions
     fsl-util.4th: FSL support files (undocumented)
     regexp.fs for regular expressions (undocumented)
     complex.fs for complex numbers (undocumented)
     fft.fs for Fast Fourier Transform (undocumented)
     wf.fs, a Wiki implementation (undocumented)
     httpd.fs, a web server (undocumented)
     status.fs, show interpreter status in separate xterm (undocumented)
     profile.fs for profiling (undocumented, incomplete)
     endtry-iferror.fs, recover-endtry.fs to ease the TRY change transition
     test/tester.fs: Now works with FP numbers (undocumented)
     test/ttester.fs: Version of tester.fs with improved interface (T{...}T).
    compat library:
     compat/execute-parsing.fs
   Speed improvements:
     automatic performance tuning on building
     static stack caching (good speedup on PPC)
     mixed-precision division is now faster
     support for int128 types on AMD64
     workarounds for gcc performance bugs (in particular, PR 15242)
     branch target alignment (good speedup on Alpha).
   
   
 User-visible changes between 0.6.1 and 0.6.2:  User-visible changes between 0.6.1 and 0.6.2:
   
 bugfixes (in particular, gforth-0.6.2 compiles with gcc-3.3)  Bug fixes (in particular, gforth-0.6.2 compiles with gcc-3.3)
   New words: LATEST, LATESTXT (LASTXT deprecated)
   Operating environment: Added optional support for a C interface built
     on the ffcall libraries (more portable and powerful than the old
     one, but still not documented).  To use it, the ffcall libraries
     have to be installed before building Gforth (see INSTALL).
   Miscellaneous: Gforth-fast now uses static superinstructions (some
     speedup on some platforms); generally this is transparent (apart
     from the speedup), but there are lots of command-line options for
     controlling the static superinstruction generation.
