Comment (by RJVB):

 I already have updated my own Qt to 5.7.1, and so yes I was planning to
 see if PyQt 5.7.1 builds using your patched SIP 4.19 . But I don't want to
 get too much ahead of the pack for ports I'm not officially involved in
 outside of the KF5 ports so if nothing else comes up you could maybe
 provide a SIP 4.18 subport, temporarily? That would allow others to follow
 the suggestion I gave in comment:19.
 It seems not very likely that applications built with PyQt5 will be using
 3rd party libraries that are also built using SIP and run into ABI issues.
 And even if there are a few that still leaves a probably larger set of
 apps that only use a bit of PyQt5

 Someone should chime in "mmol", btw. Maybe he has a brilliant idea how to
 reintroduce the missing typedef.
