[Win32utils-devel] Modification for mkmf

[win32utils-devel at rubyforge.org]

Here's a Win32API snippet for getting major and minor:

require "Win32API"

GetVersionEx = Win32API.new('kernel32','GetVersionEx','P','I')
swCSDVersion = "\0" * 128
OSVERSIONINFO = [148,0,0,0,0,swCSDVersion].pack("LLLLLa128")
GetVersionEx.call(OSVERSIONINFO)
info = OSVERSIONINFO.unpack("LLLLLa128")

major, minor = info[1,2]

Dan
