    Problem Text
    X/Open interpretation VWG/016/070792 states: "The regexp.h header is
    allowed dispensation from namespace rules since this conflicts with
    existing behaviour." As a result of this interpretation, test suite
    deficiency TSD4.011 was granted for VSX 4.2.3 and a code fix was
    added to VSX 4.2.4. The code fix appears to be incomplete.

    Our <regexp.h> header includes <stdlib.h>. Our stdlib.h contains the
    following:

    typedef struct { /* struct returned from div */
    int quot; /* quotient */
    int rem; /* remainder */
    } div_t;

    This test defines a macro

    #define quot "quot unprotected"))))))))))

    which changes the code above to

    typedef struct {
    int "quot unprotected"))))))))));
    int rem;
    } div_t;

    and the compiler complains. A permanent waiver is requested.
    Test Output
    /tset/XOPEN.hdr/misc/regexp/T.regexp 9 Failed

    Test Description:
    If _XOPEN_SOURCE is defined and no other feature test macros except
    _POSIX_SOURCE, _POSIX_C_SOURCE=1 or _POSIX_C_SOURCE=2 are defined, no
    other symbols than those defined or reserved by the XPG are made
    visible.
    This test is not executed in XPG3 mode.

    Test Strategy:
    FOR each unreserved struct/union member made visible by the header
    DEFINE a macro which will cause an error if not protected from
    expansion
    UNDEFINE those macros which correspond to allowed member names
    INCLUDE a copy of the header file modified to identify #defines
    FOR each unreserved symbol made visible by the header
    VERIFY that the symbol name is in a list of allowed names
