Yes. In my opinion the problem with autoconf is not the lack of a system-wide cache. It's that the tests can not be run in parallel. Fixing this requires a complete redesign and rewrite, which is frankly long over due. Using m4 to generate portable shell scripts was moderately cute when DJM did it fifteen years ago, but it's looking pretty old now. Ian
