Update to 6.2.4, using Matt Danielson's update to 6.2 from PR 45925.

Version 6.2.4 - May 30 2012

[BUG FIXED]
Gtags with the -f option brings segmentation fault. Now it works.
This bug exists only in GLOBAL-6.2.3.

Version 6.2.3 - May 26 2012

[BUG FIXED]
o Built-in parser: When attribute specifier appeared immediately after the
  `struct', `union' or `enum' keyword, GLOBAL could not pick up tag name.
  Now it works correctly.

[CHANGES]
New facilities:
o gtags: --single-update option support addition of a file.
o global: New --single-update option.
o gtags.el: New custom variables:
  - gtags-ignore-case
  - gtags-auto-update.
o gtags.vim: New custom variables 'Gtags_Auto_Update' (default 0).

Version 6.2.2 - March 15 2012

[BUG FIXED]
o configure: The --disable-gtagscscope option didn't avoid building gtags-cscope
  completely. So, ./configure failed when there is no curses library.
  Now it avoids building gtags-cscope completely.
o htags: Imported a patch to fix htags on Windows Vista+ (tmpfile wants to create
  its file in the root directory, which is not writable by normal users).

Version 6.2.1 - February 24 2012

[CHANGES]
New facilities:
o gtags: New --accept-dotfiles option.
o configure: New --disable-gtagscscope option.
o gtags.el: Key mapping was changed to follow "Key binding conventions" of Emacs Lisp.
  - The prefix character "\C-c" for suggested key mapping became customizable.
    If you want to invoke 'gtags-find-tag by "\C-xt", please write your .emacs file
    like follows:

        [$HOME/.emacs]
        (setq gtags-suggested-key-mapping t)
        (setq gtags-prefix-key "\C-x")

[INCOMPATIBLE CHANGES]
o gtags.el: Key mapping was changed to follow "Key binding conventions" of Emacs Lisp.
  - Policy of key mapping was changed.
  [Old] If 'gtags-suggested-key-mapping' is false, any key mapping is not done.
  [New] If 'gtags-suggested-key-mapping' is false, almost key mapping is not done.
        But "\C-m" and "\C-t" in 'Gtags select mode' are always enabled.

[BUG FIXED]
global: The -L option with '-' didn't work. Now it works.
Built-in parser:
- Pick up symbols in expression in enumerator-list as "reference or other symbol".
- C/C++ parser couldn't handle typedef of the form of 'typedef enum tag_name TYPEDEF_NAME;'
  correctly. Now, it works.

Version 6.2 - January 21 2012

[CHANGES]
New facilities:
o gtags.el: Added support for TRAMP. Now gtags.el works almost transparently with TRAMP.
  Please send a bug report to the bug mailing list.
o gtags-cscope: Enables an environment variable EDITOR allow options.
o gtags-cscope: New -i option.
o gtags-cscope.vim: New custom variable GtagsCscope_Kepp_Alive.
o globash: Added long name options:
  use, show, first, last, next, prev:   --vi, --less, --emacs, --vim, --gozilla, --noedit
  mark: --list, --edit
  cookie: --list, --edit, --menu, --warp
o gtags: Add keywords introduced in ISO/IEC 9899:2011.
  _Alignas _Alignof _Atomic _Generic _Noreturn _Static_assert _Thread_local

[INCOMPATIBLE CHANGES]
o less-global: Quoting is required for the pattern which should be interpreted by the shell.

[BUG FIXED]
The icase_path config variable didn't affect the -c command with the -P option of global.
Now it works.

Version 6.1 - October 7 2011

[CHANGES]
New facility:
o Server side GLOBAL
  You can use some shell scripts instead of global, gtags and htags.
  By this facility, you need not install GLOBAL in your client machine.

  Client machine       Network         Server machine
