The compiler does not check that type conversion operators must
have at least one argument.

It also looks like the error messages could be made more consistant
for all of the following cases.

b047 had missed error(s) as follows:
	36: int operator int ();		// ERROR
	38: base operator base ();		// ERROR
b047: FAILED
-------------------------------------------------------------------
// Check that it is illegal to declare unary operators with
// less than one argument.  Check type conversions as well
// as normal operators.

struct base {
	int member;
};

// Unary +
int operator + ();		// ERROR

// unary -
int operator - ();		// ERROR

// unary & (i.e. address of)
int operator & ();		// ERROR

int operator ~ ();		// ERROR

int operator ! ();		// ERROR

int operator ++ ();		// ERROR

int operator -- ();		// ERROR

int operator [] ();		// ERROR

int operator () ();		// ERROR

int operator -> ();		// ERROR

void* operator new ();		// ERROR

void operator delete ();	// ERROR

int operator int ();		// ERROR

base operator base ();		// ERROR
