GCC 4.9 issues an error for copysign in initializer:
In file included from tst-printf-format-p-double.c:20:0:
tst-printf-format-skeleton-double.c:29:3: error: initializer element is not a constant expression [-Werror]
{ -HUGE_VAL, -DBL_MAX, -DBL_MIN, copysign (0, -1), -NAN, NAN, 0, DBL_MIN,
^
since it can't fold "copysign (0, -1)". Replace copysign (0,-1) with -0.0.
