There's the matter of exception handling logic not being able to be placed where you might want it, too. With a simplistic C error handling facility I can store an error code and check it later when it matters or is most convenient.

Wow. I am truly staggered ... just utterly lost for words. Exceptions/RAII automatically propogate non-recoverable errors to the correct level of abstraction, error return values have to be propogated by hand.

With exceptions, I need to wrap each individual function call (and operator, etc.) in order to ensure that nothing slips past.

Holy living Christ on a bicycle... Do you really think that's how to write code that uses exceptions for error handling? If you do, please stop writing about it, because you don't know what you're talking about.
