gdk-win32: Clean Up A Bit

Browse Source 
As GLib dropped Windows 2000 support some time ago [1][2], and the current
git master already depends on a GLib release that is well after it dropped
Windows 2000 support, clean up the code a bit as we are assured that the
code will run on XP and later, plus, we have dropped XP support during
this cycle with commit b85f0cc.
