What the error message is trying to tell you is that you need the
"-fpermissive" option to CXXFLAGS if you expect the code to compile
despite the mismatched types.  Whether it will succeed or just stop
someplace else remains to be seen.

The upstream package is at version 4 already, which probably needs other
patches as a quick look at Fedora seems to indicate:
