Hello, Tom.

I'm a bit concerned regarding assumption that sizeof int never exceeds 4
bytes. While this could be true today for most C compilers, standard
[1][2] doesn't guarantee that. Perhaps we should add something like:

StaticAssertStmt(sizeof(int) <= sizeof(int32),
    "int size exceeds int32 size");

It costs nothing but could save a lot of time (not mentioning data
loss) some unlucky user.
