Shell command for generating a list of defined macros in a source file.
This list is used to display the #define directive associated
with an identifier as a tooltip. It works in a debug session with
GDB, when gud-tooltip-mode(var)/gud-tooltip-mode(fun) is t.
Set gdb-cpp-define-alist-flags for any include paths or
predefined macros.
This variable was added, or its default value changed, in Emacs 22.1.
