Hi!  Looking at the libgnutls.a installed on my system, it doesn't
have libz symbols either:

jas at mocca:~/src/gnutls$ nm -B ~/lib/libgnutls.a |grep deflate
         U deflate
         U deflateEnd
         U deflateInit2_
jas at mocca:~/src/gnutls$

Isn't the normal procedure that, if you use static linking, you have
to link directly to a library, and all its dependencies?

I think that if you use libtool to link your static application, it
should have taken care of this.
