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.
Running `configure -extra-cflags=-Wunused-parameter` triggers the problem. configure for a native build does abort but shows the error in config.log. A cross build configure for Windows with Debian stable aborts with an error. Avoiding unused arguments fixes this.
