- Shiboken headers need to be included first to get MAJOR/MINOR version flags. Without them the code would still compile, but fail the version check a few lines below assuming Shiboken is always older than 5.12 - Fix typo in cast when HAVE_SHIBOKEN_TYPE_FOR_TYPENAME is defined and remove the conditional: we have to assume typeForTypeName() always results in a valid name, as for the other implementations. There's no error handling of any kind in callers. This fixes the build on debian unstable with shiboken 5.15.
