The problem code boils down to:

  /* Structure forward decls */
  struct l_structtype_s;

  /* Typedefs */
  typedef struct l_structtype_s l_fixarray_array3[3];

which is illegal C, but perfectly valid C++, and g++ accepts it.

The structure contents are defined right afterwards, but I assume that
the typedefs are used when emitting the structure contents? We may have
to put fully defined structures first and typedefs second.
