* cygcheck.cc (dump_sysinfo): Distinguish Windows 8 and 8.1, as well

as Windows Server 2012 and 2012 R2.  Add missing commas in products
	array to avoid crashes.  Drop Windows NT4 and 2000 printouts.  Just
	call IsWow64Process, GetNativeSystemInfo, and GetDiskFreeSpaceEx
	directly, rather than loading them dynamically, since they are exported
	by all supported OS versions.  Fix questionable type usage in call to
	GetDiskFreeSpaceEx.
