* c-cppbuiltin.c (builtin_define_float_constants): Add
fp_cast parameter, pass to builtin_define_with_hex_fp_value.
Define __FLT_HAS_DENORM__, __DBL_HAS_DENORM__,
(builtin_define_with_hex_fp_value): Use fp_cast when building
(c_cpp_builtins): If flag_single_precision_constant then set
to "((double)%sL)" otherwise "%s".
