/* Emacs can read input using SIGIO and buffering characters itself,
or using CBREAK mode and making C-g cause SIGINT.
The choice is controlled by the variable interrupt_input.
Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros
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.
Another method of doing input is planned but not implemented.
It would have Emacs fork off a separate process
to read the input and send it to the true Emacs process
through a pipe. */

pre-ANSI systems. If you're using GCC on an older system, __STDC__
will be defined, but the system's include files will still say that
signal returns int or whatever; in situations like that, define
