Log Message:
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.
