[cfe-dev] Getting CXType_Int and data size == 4 for uint64_t

[Hayden Livingston via cfe-dev]

I would have thought that precisely specifying bit width would be
considered portable? Isn't that the whole point of it? vs long which
is 8 or 4 bytes depending on the OS etc?

I'm not sure where to look or what to modify to get the right size.
