Does anyone know what's so special about enums that
   if I declare an enum type to be global in file A:
       enum example {EX1, EX2, EX3};

   and I call a function and pass, say EX2: functionInB( 4, EX2 )

   and in file B I've defined that function:
     void functionInB( int num, example thisCase ){ . . . }

   but if I extern the enum in file B: extern example,
   the complier has no idea what example is: it expects
   a closing brace (")") after num,.

   So, what's the trick?--I've tried everything!

   Thanks for your time.
