4231 dnl The choice is controlled by the variable interrupt_input.

4235 dnl Emacs uses the presence of the USABLE_SIGIO macro
4236 dnl to indicate whether or not signal-driven I/O is possible. It uses
4237 dnl INTERRUPT_INPUT to decide whether to use it by default.
4239 dnl SIGIO can be used only on systems that implement it (4.2 and 4.3).
