The latest SIP tries to use the original typedef name (rather than the type
it expands to) wherever possible in the generated code. This makes it
easier to support feature specific typedefs (eg. not all platforms
implement qreal as the same time).

The change should make no difference so long as the .h files being wrapped
properly contain the typedef (and SIP properly includes those files).

So where is size_type defined in your library?
