MySQL profile_values definition doesn't match established integer length.

Just working on a profile reporting idea and spotted that the following fields appear to have incorrect type definitions:
profile_values.fid = int(11)
profile_values.uid = int(11)

These both appear inconsistant with the rest of the database (that I have seen i.e. user tables) where they are defined as int(10). The profile_fields.fid is defined as int(10) also.
