Autoconf redefines the M4 builtin macro 'm4_undefine' in such a way that
it fails if the macro that is being undefined is not already defined. To make this work under all cases and be sure that at a certain point some specific macro isn't defined we must use the following style in configure: m4_ifdef([macro], [m4_undefine([macro])])
