    Problem Summary PG4U.00061 This IR claims that fd_set is a valid structure tag.
    Problem Text
    The IR claims that fd_set is a valid structure tag.

    The XSH4.2 specification states that fd_set is defined in <sys/time.h>.
    The test suite claims fd_set to be an invalid structure name, and
    generates a name space pollution error.

    fd_set is also claimed to be invalid by test of <sys/resource.h>,
    <sys/wait.h> and <stdlib.h>.

    However, these headers legally make all symbols from <sys/time.h>
    visible. Test cases are:

    CAPIheaders/hresourc/hresourc15, CASE 34
    CAPIheaders/hwait/hwait17, CASE 25
    CAPIheaders/hstdlib/hstdlib20, CASE 45

    Review Response
    We recommend this request be refused.

    The specification states:

    The <sys/time.h> header defines the fd_set type as a
    structure that includes at least the following
    member:

    long fds_bits[] bit mask for open file descriptions

    Pursuant to this the test suite allows:

    typedef struct {
    fds_bits[_fds_howmany(FD_SETSIZE, FD_NFDBITS)];
    } fd_set;

    It does not however allow fd_set to be used as a structure tag within
    such a statement as this is not allowed by the spec. Thus the
    following statement is correctly flagged as an error:

    typedef struct fd_set {
    fd_mask fds_bits[_fds_howmany(FD_SETSIZE, FD_NFDBITS)];
    } fd_set;
