    Linked Problem Reports TIN4U.00001, (in, old, system)
    Problem Summary TIN4U.00005 Symbols defined in signal.h may be visible in the namespace when time.h is included, pending a POSIX interpretation.
    Problem Text
    As stated in TIN4U.00001:

    "(time.h, POSIX should allow symbols defined in
    signal.h to be visible in the namespace when time.h is included).

    Although the synopsis for timer_create() (POSIX.1-1996, P312, L138-141)
    shows that <signal.h> must be included before <time.h> to pick up the
    definition of struct sigevent, there are lots of synopses in
    POSIX.1-1996 that just specify <time.h>. When an application using
    routines defined in <time.h> that don't also require <signal.h> (e.g.
    clock_gettime()) is built, most compilers generate warnings about a
    dubious tag declaration for struct sigevent. This is because the
    specification for <time.h> does not require (or even allow) struct
    sigevent (and the union sigval needed to define its
    sigev_notify_function element) to be defined and does not reserve
    namespace to define elements of struct sigevent and union sigval when
    <time.h> is included. Even though these are warnings, not errors, our
    customers complain when they use standard functions from standard
    headers and don't get "clean compiles".

    In other places where this problem could occur, the C Standard and
    POSIX standards usually reserve the namespace or require that the
    needed elements be in both headers. Examples of these are:

    1. The description of <stdio.h> in the C Standard (ISO/IEC 9899-1990),
    P124, Section 7.9.1, 2nd and 3rd paragraphs requires that <stdio.h>
    define size_t and NULL in <stdio.h> as well as in <stddef.h>.

    2. The description of <mqueue.h> in POSIX.1-1996, P319, L2-4 says that
    including <mqueue.h> may essentially include <sys/types.h>,
    <fcntl.h>, <time.h>, and <signal.h> and L13-16 requires that struct
    sigevent be defined in <mqueue.h> as well as in <signal.h>."

    This failure is already covered by TIN4U.00001. However, since the
    new test output differs somewhat from the output for VSU5.0.4 as shown
    in TIN4U.00001, it is recommended that a new TIN is issued.
