Fix a typo in the code which would move the code
to the Objective C 2.0 runtime. Correctly check
for the size of area necessary to store the object (vs.
allocated area) to make a decision whether or not we
need to re-allocate.

In the new Objective C 2.0 runtime, class Object was trimmed
and no longer contains + alloc, - init, - free and - subclassResponsibility,
which we use.

Implement our own base class and use it instead of the old Object.

This should fix compilation with gcc 4.7 everywhere and clang on
Darwin.

The current code can still be built with gcc 4.6.
