  [BUG FIXES]

  - Various native trait methods would refuse "0" where they expected a
    string.  They have been fixed to allow all defined, non-reference values,
    and all objects with string, number, or boolean overloads.

  [DOCUMENTATION]

  - Moose::Manual::Construction now notes that roles can modify the BUILD sub.
    (thanks, E. Choroba!)

  [OTHER]

  - adjustments have been made to the Makefile for 'bmake', so it now works
    when not run in compatibility mode (Leon Timmermans).
