WinX is a piece of MingWin (I believe it's an add-on) that supplies
definitions and implementations of various POSIX things in terms of their
windows counterparts.

See below for details.

Thanks,

1.  interp.c includes <winx/signalx.h> to get:

2.  events.c include <winx/signalx.h> to get the same SIGUSR1 definition as
        the inter.c module.

3.  sysdep.c:
        (a) includes <winx/signalx.h> to get SIGUSR1, SIGUSR2, SIGCHLD, SIGIO,
                and SIGPIPE definitions.
        (b) includes <winx/sys/waitx.h> to get implementation of "fork", wait,
                pid, getpid.  I'm not sure how good these implementations are.

4.  tcp.c includes winsockx.h to get definitions for various POSIX error codes
in terms of the WINDOWS standard
