Issue 5

    The following sentence is deleted from the DESCRIPTION: "The
    value of errno is 0 at program start-up, but is never set to
    0 by any XSI function". The DESCRIPTION also no longer states
    that conforming implementations may support the declaration:

       extern int errno;

Issue 6

    Obsolescent text regarding defining errno as:

       extern int errno

    is removed.

    Text regarding no function setting errno to zero to indicate an
    error is changed to no function shall set errno to zero. This
    is for alignment with the ISO/IEC 9899:1999 standard.
