Yeah, on reflection I agree with that.

My goal here is to get rid of all internal uses of AC_EGREP_CPP and
AC_EGREP_HEADER.  I don't think we should aggressively add to the
list of -Wobsolete warnings in what's supposed to be a bugfix release.
Therefore, how about I revise this patch to remove the case for
freebsd* | darwin*, and make no other changes?
