I am also trying to build GRASS 4.1 on an SGI but it is an Indigo2 Impact with
an R4400 CPU running IRIX 5.3. However, I did have the same problem and the
solution I used is as follows:

In the file mark.c there is a function called "get_point2" which calls the
"screen" function. The "screen" function is defined after the "get_point2"
function but it is declared inside the "get_point2" function. The problem is
that the declaration for the "screen" function is not recognized by the loader
since it is inside a function. To fix this you simply need to declare the
"screen" function before the "get_point2" function. The code would look
something like the following:

        static
        int screen();

        static
        get_point2 (east, north)
        ...

This fix solved the compilation error but I have not tested the programs yet.
