  o Code simplifications and refactoring:
    - Use Ville Laurikari's implementation of AX_CHECK_SIGN() to determine
      the signs of types during autoconf. This is better than our old
      approach, which didn't work when cross-compiling.
Use a nicely written autoconf macro to determine the sign of a type This beats our old implementation, which wouldn't work when cross-compiling 2013-02-07 22:23:48 +01:00			`o Code simplifications and refactoring:`
