  *** Note: ***
  There is currently one importants side effect when doing static linking.

  If you include a function statically than its required to be present
  in the supplied DLLs of your OS and Hardware.
  This means if the DLL is not present your program will not run.
  In Win95 it appears that you will be informined you about
  the name of the first missing symbol while loading the executable.
