   User-visible changes between 0.6.2 and 0.6.9 (up to 2007-09-12):
   
   Installation:
     support for DESTDIR, POST_INSTALL, INSTALL_SCRIPT
     report performance and functionality problems at end of "make"  
   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 (complete?)
   Invocation:
     New flags --ignore-async-signals, --vm-commit (default overcommit)
   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 (incomplete, documentation probably not up-to-date):
     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 (libcc C interface)
     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)
     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)
     support for use of libffi (supplied with gcc) (undocumented) and
     a C-compiler-based approach (requires C compiler at run-time) (incomplete).
   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:
     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).
