Component:  topology  |     Version:  trunk

 Topology tests fail. Most are likely due to geometries with an explicit
 SRID=-1 being compared with geometries with an implicit SRID=0.

 Considering both -1 and 0 as "unknown" would likely fix these cases.
 BTW, I suggest we have ST_Srid() return NULL for the unknown case.
