How about the following:

Use DEFVAR_LISP to define a Lisp variable with initial value of Qnil.

In some preloaded Lisp file, say subr.el, give that variable a value,
a list of symbols that name the events we currently don't consider
relevant for throw-on-input.  (Those symbols will have to be invented,
e.g. 'focus-in' for FOCUS_IN_EVENT, etc.)

In kbd_buffer_store_buffered_event, where we set Vquit_flag depending
on Vthrow_on_input, examine the value of that list variable, and
ignore any events that have their symbols in the list.
