+;; You don't need to know about annotations to use this mode as a debugger,

+;; Annotations section in the GDB info manual.
+;;
+;; GDB developers plan to make the annotation interface obsolete. A new
+;; interface called GDB/MI (machine interface) has been designed to replace
+;; it. Some GDB/MI commands are used in this file through the CLI command
+;; 'interpreter mi <mi-command>'. A file called gdb-mi.el is included with
+;; GDB (6.2 onwards) that uses GDB/MI as the primary interface to GDB. It is
+;; still under development and is part of a process to migrate Emacs from
+;; annotations to GDB/MI.
+;;
+;; Windows Platforms:
+;;
+;; If you are using Emacs and GDB on Windows you will need to flush the buffer
+;; explicitly in your program if you want timely display of I/O in Emacs.
+;; Alternatively you can make the output stream unbuffered, for example, by
+;; using a macro:
+;;
+;; #ifdef UNBUFFERED
+;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
+;; #endif
+;;
+;; and compiling with -DUNBUFFERED while debugging.
;;
;; Known Bugs:
;;
+;; TODO:
+;; 1) Use MI command -data-read-memory for memory window.
+;; 2) Highlight changed register values (use MI commands
+;; -data-list-register-values and -data-list-changed-registers instead
+;; of 'info registers'.
+;; 3) Use tree-widget.el instead of the speedbar for watch-expressions?
+;; 4) Mark breakpoint locations on scroll-bar of source buffer?
+;; 5) After release of 22.1 use '-var-list-children --all-values'
+;; and '-stack-list-locals 2' which need GDB 6.1 onwards.
