Thanks for the one posting that suggested a solution.  However, I found
the answer, and since it is a common one I felt a further posting on the
subject is called for.

In this case and others, a file contains this sort of code:

    ...
    x = DoSomething(...);
    ...

static int DoSomething(...) { ... }

On an SGI system this causes DoSomething to be an unsatisfied external
unless the function occurs before the invocation, or at least is
declared before it is invoked.  Apparently on other systems this is
acceptable.

I don't know whether the SGI touchiness agrees with the standard, but
this is a real pain.  Does anyone have a general solution?
