Will you always be building on a machine that has dladdr? If so,
then you can get rid of the lines:
struct dl_info;
extern int dladdr(void *, struct dl_info *);
and include <dlfcn.h> instead.
If the code might be built on an older system, then you'll need to
grab the definition of "struct dl_info" from the patches I posted.
