Sure.  First of all, you forgot the `void' before the formal
declaration of (*f[])(int, int) in function fill.

Secondly, cfront 1.2.1 and G++ have problems grokking complex
pointer-to-function-etc declarations.  Putting the keyword `auto' in
strategic places provides enough context to the parser so that the
program is properly recognized.  The following revised version
compiles correctly with both cfront 1.2.1 and G++.

I don't know if cfront 2.0 fixes this problem.

#include <stream.h>
void junk( int a, int b )
{
        cout << a << "\n" << b;
}

void fill( auto void (*f[])(int, int) )
{
    int i;
    for ( i = 0; i < 128; i++ )
      f[i] = junk;
}

main()
{
     auto void (*func_tbl[128])(int, int);

     fill( func_tbl );
}
