Now answering the point you actually raised:

I agree. If you want to use our qint128 API, you should use a standard C++ 
library that knows about it too. You can mismatch at your own risk.

That only brings the problem that QtCore and QtTest must support int128 if the 
library *can* support it. We must either switch to non-strict mode in 
compiling those two libraries or we must ignore our own flag in them. Neither 
option is appetising.
