      Dunno.  there might be something changed in the
        newer gcc but no idea so far it works and apparently no fault we
        can see such errors. so just suggesting to see the outcome how
        it looks like with the newer gcc.

                      You can see how your gcc generate the
                        preprocessed source code with -E. I can build it
                        with:
                      $ gcc --version
                      gcc (GCC) 6.2.1 20160916 (Red Hat 6.2.1-2)

                                    patch and it has an error. please
                                    check.

                            I  loaded a fresh tar package http://fontconfig.org/release/fontconfig-2.12.1.tar.bz2

                            Are you using a different source package?

              So this is a preprocessor problem of my newer gcc?

    Akira,

    
    your patch "Avoid conflicts with integer width macros from TS
    18661-1:2014" of today

    solved the problem.

    
    Fontconfig git now compiles without error.
