    ada: Silence unused parameter warning on linux
    
    In __gnat_locate_exec_on_path (char *exec_name, int current_dir_on_windows)
    the recently added second parameter is for windows only. On non-windows
    platforms its usage is removed by the preprocessor and the compiler
    reports unused parameter.
    
    gcc/ada/ChangeLog:
    
            * adaint.c: void parameter on non-windows platforms
