  Hi,
  I'm using CYGWIN g++. I'm having trouble making an API call the
WindowFromPoint function.
  Here is my code.

  FILE: t.cc
  #include <windows.h>
  int main () {

  POINT p;
  p.x=200;
  p.y=200;

  HWND window_handle;

  window_handle = WindowFromPoint(p);

  return 0;
  }

  Here is the error message I'm getting:
  C:\DOCUME~1\jeff\LOCALS~1\Temp\ccIIB5F0.o(.text+0x22):t.cc: undefined
reference to 'WindowFromPoint@8'

  Could someone please tell me
  1)What this error means and
  2)What I need to do to fix it
  Thank you
  Jeff
