* libc/include/stdlib.h (strtof, strtoll, strtoull, strtold): Also
	prototype if C++11 or later.
Revert to original patch
	* hires.h (hires_ns::nsecs): Declare with bool parameter.
	* times.cc (hires_ns::nsecs): Take bool parameter.  If set to true,
	don't use prime value (== return system wide absolute value).
