True, but your change does not compile on Windows. In image.c:

#  if LIBRSVG_CHECK_VERSION (2, 46, 0)
DEF_DLL_FN (void, rsvg_handle_get_intrinsic_dimensions,
            RsvgHandle *, gboolean *, RsvgLength *, gboolean *,
            RsvgLength *, gboolean *, RsvgRectangle *));

The 3rd argument should start with a left paren.
