        * libm/math/ef_scalb.c:  Replace isnanf() (pre-C99 function call) with
        isnan() (C99 macro).
        * libm/math/wf_log.c:  Ditto.
        * libm/math/wf_j0.c:  Ditto.
        * libm/math/wf_sqrt.c:  Ditto.
        * libm/math/wf_pow.c:  Ditto.
        * libm/math/wf_fmod.c:  Ditto.
        * libm/math/wf_remainder.c:  Ditto.
        * libm/math/wf_scalb.c:  Ditto.
        * libm/math/wf_atanh.c:  Ditto.
        * libm/math/wf_cosh.c:  Ditto.
        * libm/math/wf_acos.c:  Ditto.
        * libm/math/wf_acosh.c:  Ditto.
        * libm/math/wf_jn.c:  Ditto.
        * libm/math/wf_log10.c:  Ditto.
        * libm/math/wf_asin.c:  Ditto.
        * libm/math/wf_j1.c:  Ditto.
        * libm/common/sf_isnan.c:  Add #include <ieeefp.h>, fix comment.
        * libm/common/sf_isinf.c:  Add #include <ieeefp.h>, adjust comment to
        match that from s_isinf.c.
        * libc/include/machine/ieeefp.h:  Simplify isinf and isnan macros to
        remove un-necessary extension use (in a similar manner to as was
        recently done in math.h).
        * libc/include/math.h:  Remove isnanf and isinff prototypes (are in
        ieeefp.h).
        * libm/machine/spu/sf_isinf.c:  Fix comment (remove <math.h>).
