   Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)

   Emacs uses the presence or absence of the SIGIO macro to indicate
   whether or not signal-driven I/O is possible.  It uses
   INTERRUPT_INPUT to decide whether to use it by default.

   SIGIO can be used only on systems that implement it (4.2 and 4.3).
   CBREAK mode has two disadvantages
     1) At least in 4.2, it is impossible to handle the Meta key properly.
	I hear that in system V this problem does not exist.
     2) Control-G causes output to be discarded.
	I do not know whether this can be fixed in system V.
