    Problem Text
    This test may fail because, in certain specific circumstances, function
    prototypes are not required in this version of the spec.

    Interpretation 1170/152 has determined that complete prototypes are not
    required to be present in the header files. These tests are now
    testing for non-XPG4 required behaviour. The applicable portions of
    the interpretation are below.

    [Request text starts]

    Is there a normative XPG requirement for XPG4 functions (in
    the appropriate headers) to be declared using full function prototypes?

    [Resolution response]

    There may not be a normative requirement, but the Base WG believes that
    they should be encouraged. They are required in 9945-1:1990. If POSIX
    conformance with standard C is also being claimed, POSIX function
    prototypes must be present, and waivers should be granted if requested
    for non-POSIX functions, otherwise function prototypes are not required
    and waivers should be granted if requested. This issue will be
    addressed in XPGnext, in which it is recommended that function
    prototypes for all functions, should be required. The conformance
    requirements should be extended to inculde a requirement to be
    POSIX.1/.2 conforming. The test suite should continue to test for the
    presence of function prototypes, and issue waivers where necessary.

    Users for whom this is an issue should specify UNIX 95 conformance and
    FIPS-2 (or POSIX.1) conformance as well.


    (For testing PINs could be granted for those implementations
    that dont have prototypes for non-POSIX functions for those
    folks claiming Spec1170 and POSIX).


    Test Output
    TEST CASE: math.h

    TEST PURPOSE #11
    The function int ilogb(double x) shall be declared
    with the correct prototype in math.h.
    ERROR: ilogb not defined
    11 FAIL

    TEST PURPOSE #13
    The function double logb(double x) shall be declared
    with the correct prototype in math.h.
    ERROR: logb not defined
    13 FAIL

    TEST PURPOSE #17
    The function double nextafter(double x, double y)
    shall be declared with the correct prototype in math.h.
    ERROR: nextafter not defined
    17 FAIL
