commit d435569cd626bccb9c27361202a279d0fd7fce88
Author: Joseph Myers <joseph@codesourcery.com>

    Fix sincos errno setting (bug 15467).

    This patch makes sincos set errno to EDOM when passed an infinity,
    similarly to sin and cos.

    Tested for x86_64, x86, powerpc and mips64.  I don't know if the
    architecture-specific implementations for ia64 and m68k might need
    corresponding fixes.
