% cat echo-args.c
#include <stdio.h>

main(int argc, char *argv[])
{
     if (! argc) {
          printf("There are no arguments.\n");
     }
     else {
          printf("The arguments are:");
          while (argc--) {
               printf(" %s", *argv++);
          }
          printf("\n");
     }
     exit(0);
}
% cat use-echo-args
#!/tmp/echo-args

exit 0
% ./use-echo-args foo bar baz
The arguments are: echo-args ./use-echo-args foo bar baz

This is on BSD 4.3; I doubt it's significantly different on other platforms
that allow #!.  I guess this is why "#!/bin/awk -f" works.
