cfront screws up also, here's the diagnostics from 1.2.1:

----------------------------------------
CC  foo.c:
"foo.c", line 13: warning:  second_class_object used but not set
"foo.c", line 13: warning: no value returned from another_function()
cc    foo.c..c /cd/ua/schmidt/lib/sun4/mylib.a /cd/ua/schmidt/lib/sun4/strlib.a -lC
"foo.c", line 12: undefined structure or union
mv: foo.c..o: Cannot access: No such file or directory
----------------------------------------

The last error is propagated through to the C compiler!  Here's a
portion of the generated C source code:

----------------------------------------
"foo.c", line 13: warning:  second_class_object used but not set
"foo.c", line 13: warning: no value returned from another_function()

struct second_class {	/* sizeof second_class == 2 */
   char _dummy; 
};

struct first_class _second_class_some_function ();

int another_function ()
{ 
struct second_class _au1_second_class_object ;

_second_class_some_function ( & _au1_second_class_object ) ;
}
;
