| | | | | | | | | | * 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.
