 Log Message:
 Update to Gforth 0.7.0.
 
 User-visible changes between 0.6.2 and 0.7.0:
 
 Requirements:
   At run-time requires libtool and gcc (for the libcc C interface) and
                        gdb (for the disassembler (SEE)) on some platforms.
 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, PPC64: disassembler and assembler
   Gforth EC: R8C, 4stack, misc, 8086 work
   MacOS X: better support
 Invocation:
   New flags --ignore-async-signals, --vm-commit (default overcommit)
             --print-sequences
 Forth 200x:
   X:extension-query: produce true for all implemented extensions
   X:required REQUIRED etc. (not new)
   X:defined: [DEFINED] and [UNDEFINED]
   X:parse-name: PARSE-NAME (new name)
   X:deferred: 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
   X:fp-stack (not new)
   X:number-prefixes (partially new, see below)
 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
 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
 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).
