FWIW, I agree with Albert.  Noone can predict how long strings will be
computed for the AC_SUBST variables.  So we should find a working sed,
to be safe.

Of course, AC_PROG_SED can be optimized, and I plan for that.  For example,
we should 1) walk the path to look for a GNU sed installed as "sed" or "gsed"
2) walk the path again, doing the expensive test; as soon some sed passes
the maximum, we can quit, noone can be better.

You could perhaps record this work as a necessary prerequisite for the next
full release, but please accept Alberts patch.

Have a nice day,
