Kenn,

<http://cygwin.com/acronyms/#CYNUX>.  Cygwin is not even an OS.  Cygwin is
an *emulation layer* on top of Windows.  Windows' idea of privileged
instructions likely differs from Linux's.  Try compiling your code with
"-mno-cygwin" -- you will still get that popup.  You might have better
luck asking on a Win2k forum, as this is clearly a Win2k issue.
