C-x C-a is GUD prefix. gdb-mi.el is based on GUD, so it uses its
keybindings too.

Which section of Emacs manual says that?

`C-c LETTER` keyspace is reserved for users' needs, as stated in section
«D.2 Key binding conventions» of Emacs Lisp manual.

You can type C-x C-h and see that pretty much of C-x C- keychords are
already occupied by default global bindings.
