Hi Jakub,

I did not add any environmental variables nor I used any specific option. If I
stay inside the gcc-6.4 project folder I presume the command "make check" must
invoke gcc-6.4 but not gcc-4.8 (which is the system default).
Could you suggest a workaround to run all the tests using gcc-6.4 before the
command "sudo make install" was done?
