It looks to me that g++ treat this file as C++ file and complains
about the prototypes. What will happen if you compile it manually with
gcc? Note that g++/linux can compile this file without problem.
gcc works, g++ reports error.
$ g++ --version

In my view the testfile should declare the correct prototype.
