     Compiler error C2035
 
     struct/union 'identifier' : unknown size
 
     The given structure or union had an undefined size.
 
     Usually this occurs when referencing a declared but not defined
     structure or union tag.
 
     For example, the following causes this error:
 
          struct s_tag *ps;
          ps = &my_var;
          *ps = 17;    /* This line causes the error */
