SWIG: GCC compile errors with unsigned char when using the compactdefaultargs or kwargs feature

Hi,

I have an error appearing during compilation of the SWIG output file 
when I try to use either or both of the "compactdefaultargs" and 
"kwargs" features when using unsigned char's.

This is with swig-4.0.1-3.fc31.src.rpm and GCC 9.3.1 on Fedora31.

I get the GCC error:

bds_wrap.cpp: In function ‘PyObject* _wrap_new_BArrayBUInt8(PyObject*, 
PyObject*, PyObject*)’:
bds_wrap.cpp:2947:40: error: expected primary-expression before ‘unsigned’
  2947 |   unsigned char arg1 = (unsigned char) unsigned char() ;

A simple example is shown below. If I use single keyword types like 
"int", "char" all is fine.

Any idea what I am doing wrong (G++ options or is this a bug in SWIG ) ?
