?? Do you mean, you want to use gcc 13 with some specific options, in order to test whether gcc 10 can compile the package? This is not going to work, because we use #if tests on __GNUC__ and __GNUC_MINOR__ in dozens of places. The only way to see if gcc 10 can compile the package is to use gcc 10. Bruno
