This works (without complaint):

# test script
function testscript
    say_hello;
endfunction

function say_hello
    fprintf('Hello !\n');
endfunction


And this works (with complaint):

# test script
function say_hello
    fprintf('Hello !\n');
endfunction

say_hello;


The file is being parsed from top to bottom, apparently stopping when it 
finds an unresolved function name.  So, by that logic, the following 
should work:

# test script
function testscript
    if (0)
        say_hello;
    endif
endfunction

say_hello;

function say_hello
    fprintf('Hello !\n');
endfunction

It parses without error, but doesn't produce an output.  What one can do 
if they just try.  :-)
