          Issue ID: 22260
           Summary: importC: Error: struct `foo.Foo` no size because of
                    forward reference

Given the following C code:

struct Foo* foo(void);

typedef struct Foo {
    int x;
} Foo;

foo.c(1): Error: struct `foo.Foo` no size because of forward reference

The compiler then segfaults.

Interestingly, changing it to 

struct Foo* foo(void);

struct Foo {
    int x;
} Foo;

Has the same behavior.
