Here's another funny in cfront 2.0's handling of enum types. Consider
the following little program:

#include <iostream.h>

enum en1 { val1, val2 };

inline ostream& operator<< ( ostream& s, en1 v )
{
	s << ( v == val1 ? "val1" : "val2") << "\n";
	return s;
}

main ()
{
	cout << val1 << "\n";
}

When compiled and executed this produces the output:
 0

Thats the value of the enum as an int - the inline operator for the
type is not used. However if the line with cout in it is replaced by

	cout << "" << val1 << "\n";

Then the output is the expected:
 val1

What's going on here? It's really puzzling
