[patch/rfa] xm-aix4.h cleanup

[Joel Brobecker <brobecker at gnat dot com>]

Peter, Kevin,

Based on a previous discussion, and Peter's testing, do you think I can
commit the attached patch? I am currently testing it on our 2 AIX
machines (4.3.2 and 5.1). I would like to commit it once I have the
results, provided they are positive (I expect them to be, given Peter's
reports of his own testing).

        General cleanup of the AIX xm include file:
        * config/xm-aix4.h (fd_set): Remove undefine.
        Remove include of <sys/select.h>.
        (HAVE_TERMIO): Remove define.
        (USG): Likewise.
        (NULL): Remove redefine.
        (vfork): Remove define.
        (termdef): Remove.
        (SIGWINCH_HANDLER): Remove.
        (SIGWINCH_HANDLER_BODY): Remove.

This leaves:

  . FIVE_ARG_PTRACE: Will become OBE thanks to a patch from MarkK.

  . USE_O_NOCTTY: I think the idea for that one is to always use O_NOCTTY,
    regardless of the system. So the macro becomes moot. Will send a patch.

  . #pragma alloca: Need to continue the discussion.

All in all, I think we can get rid of that file within the next 2 weeks.

Thanks,

Joel
