Can this problem be addressed a bit better by using GetProcAddress only inside 
#ifndef HAVE_GETSYSTEMTIMEPRECISEASFILETIME code on builds for MS-Windows 7 and 
earlier, and directly using GetSystemTimePreciseAsFileTime on builds for 
MS-Windows 8 and later? That should fix the warning on builds for newer 
MS-Windows, which might be good enough.

If we do this in Emacs builds, it should be done only for MS-Windows since the 
warning is generally useful on other platforms.
