Clang 8.0.1 is used!

It seems Your fix works, but I cannot test it, since I simply don't know how to regenerate Makefiles after modifying .am files (automake wants configure.ac, running it from root dir does nothing in subdirs)... :( BUT! Problem was solved by manually adding $(GIO_LIBS) and $(GIO_CFLAGS) to corresponding Makefiles, so I consider this patch will work. After I fix gsymcheck, same problem appeared with the gnetlist-legacy, then with utils/gschlas... It seems ALL .am files in all 'src' subdirs must be modified.
