*** Error code 1

Here it does not mention 'machdep_sys_lseek' but this is the immediately
preceeding function which defines __syscall.

On my machine if you have the code...

int a(char *p)
{
    extern char *f();

    p=f();
}

int b(int c)
{
    c=f();
}

It complains with 

q.c: In function `b':
q.c:10: warning: type mismatch with previous external decl
q.c:3: warning: previous external decl of `f'

So here the function prototype for 'f()' is not only scoped within function
'a()' but appears to be acting globally.

Roger
