commit d435569cd626bccb9c27361202a279d0fd7fce88

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.
