I received some complaints saying in mingw it was"requiring windows 8" for a certain library.

"Entry point not found, GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll".

mingw appears to have the following:

#define _WIN32_WINNT 0x502
#define _WIN32_WINNT_WIN8 0x0602

Perhaps the following patch?  Thanks! :)

Oops looks like it might be more like the following. Thanks.
