commit be4830bf94e1159b00c4cc97c084c6e4765a61ae

    Define __USE_KERNEL_IPV6_DEFS macro for non-Linux kernels

    Commit 1c1e7fb6 changed the __USE_KERNEL_IPV6_DEFS tests from 'ifdef'
    to 'if'. As inet/netinet.in.h is a generic file, this causes a warning
    on non-Linux kernels (for example Hurd). To fix that define it in the
    generic bits/in.h file.

    Changelog:
        * bits/in.h (__USE_KERNEL_IPV6_DEFS): Define to 0.

    ppc: Fix modf (sNaN) for pre-POWER5+ CPU (bug 20240).

    Commit a6a4395d fixed modf implementation by compiling s_modf.c and
    s_modff.c with -fsignaling-nans. However these files are also included
    from the pre-POWER5+ implementation, and thus these files should also
    be compiled with -fsignaling-nans.

    Changelog:
        [BZ #20240]
        * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/Makefile
        (CFLAGS-s_modf-ppc32.c): New variable.
        (CFLAGS-s_modff-ppc32.c): Likewise.
        * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile
        (CFLAGS-s_modf-ppc64.c): Likewise.
        (CFLAGS-s_modff-ppc64.c): Likewise.
