#1913: PyUFunc_RegisterLoopForType doesn't work for custom data types

 I upgraded from NumPy 1.5 to 1.6, and found that ufuncs on my custom array
 data type stopped working (specifically == and !=). I don't think I'm
 doing anything wrong, but it's possible that something about the API has
 changed here. For reference, the code where I'm attempting this looks like
 so (minus some preprocessor magic):

 {{{
     HANDLE_NPYTYPE = PyArray_RegisterDataType(descr);

     types[0] = types[1] = HANDLE_NPYTYPE; types[2] = NPY_BOOL;
     PyUFunc_RegisterLoopForType(eq, HANDLE_NPYTYPE,
                                 Arr_equal,types,0);
 }}}
