There may be more, but the ones I noticed are related to the error/warning handlers. These handlers are not thread safe. There are also some non-const static variables used in the library. It would be good to decide if libtiff should be thread safe. If so, everything needs to be naturally re-entrant, or support for locks needs to be added in a few places.
