I might get some mileage out of that. No, we removed it years ago. Different configure.ac scripts use identical variable names in the cache to store the result of tests that are not exactly the same. It was causing too much breakage, so we removed it. commit 5f71fc1f19c21676f029b63499e0341a89cf2049 Author: Thomas Petazzoni Date: Thu Nov 4 20:31:25 2010 +0100 Remove support for shared configuration cache The configuration cache shared between packages, while being in principle a nice idea to speed-up the configuration of packages by avoiding repetitive identical checks, turned out to be unreliable due to the subtle differences between similar but not identical checks in different packages. After spending some time trying to fix those, we concluded that supporting the shared configuration cache is definitely too hard and too unreliable, and that we'd better get rid of it altogether. This patch therefore removes the shared configuration cache infrastructure and usage.
