  Removed some unnecessary undef INTERRUPT_INPUTs from src/s
  
  * src/s/bsd-common.h, src/s/cygwin.h: No need to undefine INTERRUPT_INPUT,
  since nothing has defined it on these platforms.

-/* 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. */
