Hi Bruno,
I like the idea of the patch, yet several people proposed patch along
this way, but I don't like the implementation. There's a lot of hair
which is due to the fact that you want to cache low level details,
such as what you computed. I think this is not right, you should
cache what you look for, not how, and anyway, that's way too much hair
for Autoconf.
In addition, the style you used is very much 2.13 like, but it is
completely different from the style used for CVS Autoconf. You can
delete almost all your `dnl's, use `#' for comments, not `dnl' etc.
Finally, you used changequote, which is eradicated from Autoconf, or
almost.
