[Jon <jon.forums@gm...>]

I slip-streamed Jacek's patch into time.h and successfully built go1.4
flavors (windows/amd64, windows/386, linux/amd64, linux/386,
darwin/amd64, darwin/386) from my local C:\Apps\go-git repo.

I currently don't use the MSYS2 mingw-w64-{i686,x86_64}-go pkgs. Now
that I know about the them I'll try to find time to look at the
PKGBUILD's
