I think letting AC_PREREQ affect _any_ macro semantics is a really bad idea (except of course: let autoconf fail if the version is too old). Here's why: that AC_PREREQ could be hidden in some third- or fourth-party macro imported from whereever, and there is no control by the configure.ac author (or macro file author) over the choice of semantics. Or maybe I completely misunderstood the remark. ;-) Cheers, Ralf
