;;; Commentary:
;; 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.
+;;
