Yes, but only internally. The internal ABIs don't matter, they are not
built with different compilers, it doesn't matter if the size/encoding
of things changes when you switch compilers or the configuration.
However, when you export something in the public ABI you need to make
sure it's the same on all compilers with all configurations.
