But that means that if a decision is later made to switch to, say, 2.61
but not 2.62, this silently regresses. If you use the construct I
posted, along with the correct version number for each macro
replacement, you ensure that you don't regress, and that eventual
improvement of even newer Autoconf versions are picked up.
