Again, about bug 389343. libgsasl checks with (see gl/m4/gss-extra.m4) AC_CHECK_FUNCS([GSS_C_NT_HOSTBASED_SERVICE]) obviously, that can't work if GSS_C_NT_HOSTBASED_SERVICE is simply a preprocessor define.
Sorry, I forgot about bug 359005. *** This bug has been marked as a duplicate of bug 359005 ***
