I'd do this.  Add this to your header:
        extern char genxDEFAULT_NAMESPACE[1];
and this to your implementation:
        char genxDEFAULT_NAMESPACE[1] = { 0 };
and then users do
        int genxDeclareNamespace(w, "urn:foo:bar", genxDEFAULT_NAMESPACE);
And then you do a pointer comparison to see if users passed in default.

BTW, the API doesn't have const-correctness yet.
        /r$

Again, a new "pointer constant" will remove the need for a new function.
