I just checked in a change so that Octave does not set
warn_matlab_incompatible to true when using --traditional.

For now, you can add

  warn_matlab_incompatible = false;

to your ~/.octaverc file.

The warnings only happen once because they are generated with the
functions you are using are compiled, but not when they are executed.

BTW, the --traditional option now only sets the following things:

  * always behave as though starting with --persist option

  * set the following built-in variables:

    PS1 = ">> "
    PS2 =  ""
    beep_on_error = true
    crash_dumps_octave_core = false
    default_save_format = "mat-binary"
    fixed_point_format = true
    page_screen_output = false
    print_empty_dimensions = false
    warn_function_name_clash = false

so it seems there are only two substantial settings here (the default
format for save files and the --persist option).
