[PATCH] Fix declaratons of conditionally defined functions

[Ben Woodard <woodard@redhat.com>]

Functions relating to zip archives are declared but are never compiled
when --enable-zip-archive=no, the default.

This makes sure that they are not declared when they won't be defined
due to conditional compilation.
