jdunn%netscape.com 01a246e76f AIX's new compiler, xlC5.x, doesn't allow the use of "friend" to declare
a function prototype.  So we have to decare the function and then
declare it a friend.  When Default arguments are used, they need to
be specified in the function prototype and NOT in the friend declaration.
