Compiler Error C2186

'operator' : illegal operand of type 'void'

The operator has a void operand.

The following sample generates C2186:

// C2186.cpp
// compile with: /c
void func1( void );
int  func2( void );
int i = 2 + func1();   // C2186 func1() is type void
int j = 2 + func2();   // OK both operands are type int
