* autoload.cc (GetSystemTimePreciseAsFileTime): Define.

Browse Source 
* times.cc (GetSystemTimePreciseAsFileTime): Temporarily declare here
	to workaround missing definition in 32 bit w32api headers.
	(get_system_time): New always inline function to call either
	GetSystemTimePreciseAsFileTime or GetSystemTimeAsFileTime on a per OS
	basis.  Call throughout instead of GetSystemTimeAsFileTime.
	* wincap.h (wincaps::has_precise_system_time): New element.
	* wincap.cc: Implement above element throughout.
