Types with multiple keywords result in broken code

Trying to use shiboken2 for my project I get the following error when compiling the resulted source file:

error: expected primary-expression before ‘unsigned’ 

The code looks as follows:

if (PyErr_Occurred())
     return unsigned int(0);

Looks like Shiboken forgets to add some braces around unsigned int.

$ llvm-config --version
