Problem compiling example in the book

[John Heiden]

This isn't entirely a BIND issue, but recently I bought "the book" by
Paul Albitz and Cricket Liu.  (Very good book, by the way.)

Anyway, I am trying to compile the example in the book, and I am
unable to.  I am trying to compile with GCC 3.0 under SPARC
Solaris 7.  Here's what I get:

checksoa.c: In function `queryNameServers':
checksoa.c:435: warning: passing arg 1 of `ns_name_skip' from
incompatible pointer type

I have tried to compile two different ways (same results):

gcc -I/usr/include -o checksoa.exe checksoa.c
gcc -o checksoa.exe checksoa.c

I have to say, I don't have as much experience with gcc as I would
like.

Is there a place I could just download the code from?  After typing for
quite a while, I found I made 3 typos.  Is it possible I overlooked
another
typo?  Or is there maybe a typo in the book?

Thank you much for your time on this.
