Silence a gcc-4.5 warning for a tautological assert.
Sadly, we can't do this in the ASSERT() #define itself, as in GCC
versions up to 4.5 warning pragmas are global, setting them in any
place in the file affects the entire compilation unit no matter where
you specify it.
GCC 4.6 and new Clangs allow you to flip warnings as often as you please,
so we'll be able to do this properly then.
