This seems like a very good idea. We should turn it on in the waf
builds, if there are issues turning on this additional feature in the
autoconf builds then this can be handled by those maintaining that build
As this is an additional feature (and a very desirable one) I see no
reason it cannot be dealt with in just waf for now, as that is what you
have working and tested.
