+
+The configure script fails because it tries to compile small C programs with a main function which is declared with arguments `argc` and `argv` although those arguments are unused.
+
+Using the same compiler flag for a native build (`./configure --disable-werror --extra-cflags=-Wunused-parameter`) shows the same errors in `config.log`, but surprisingly does not fail."""
