    Source file:
    
    	extern "C" {
    	    extern void foo (struct frob *);
    	};
    
    	struct frob {
    	    int a, b;
    	};

and it chokes.... Too bad :->. In any case, you *should not* put a semicolon
at the end of an extern "C" block. This is also the likely reason of the
core dump, because using 'struct some *' before having seen 'struct some {
....' is legal and without problem in both C and C++, or else mutually
"recursive" data structures would not be possible.
