/* exp_console.c - grab console.  This stuff is in a separate file to

avoid unpleasantness of AIX (3.2.4) .h files which provide no way to

reference TIOCCONS and include both sys/ioctl.h and sys/sys/stropts.h

without getting some sort of warning from the compiler.  The problem

is that both define _IO but only ioctl.h checks to see if it is

defined first.  This would suggest that it is sufficient to include

ioctl.h after stropts.h.  Unfortunately, ioctl.h, having seen that _IO

is defined, then fails to define other important things (like _IOW).

Design and implementation of this program was paid for by U.S. tax

dollars.  Therefore it is public domain.  However, the author and NIST

would appreciate credit if this program or parts of it are used.
