Two possibilities:

1. Upgrade to AIX 4.1 and the current version of xlc, which does what you
   need:

    sp054:~/tmp 9> cat test.c
    void foo(void)
    {
	bogus();
    }
    sp054:~/tmp 10> xlc -qinfo -c test.c
    "test.c", line 3.5: 1506-304 (I) No function prototype given for 'bogus'.

2. Use gcc, which is freeware:

    sp054:~/tmp 11> gcc -Wall -c test.c
    test.c: In function `foo':
    test.c:3: warning: implicit declaration of function `bogus'

Given your email address, the first alternative might be free for you,
as well.
