It's been pointed out to me that the English of my message may be inappropriate. I have not intended to annoy anyone, and would like to apologize if it was understood that way; keep in mind I am not a native speaker. Please read above as So the bottom line is that it is advantageous to always use this new notation if dealing with Autoconf 2.50+ generated scripts, as then configure can record this information easily; it will be easier for you to recreate the same configuration later. To give another useful example of this, happened to me yesterday: I updated a software package that uses a 2.13-generated configure script. I kept the build tree from the installation from more than 2.5 years ago, to be able to easily recreate a new build with identical features. It needed a couple of environment variables for this. Would this package use Autoconf-2.50+, it would have sufficed to keep the config.status file, and a simple ./config.status --version would have told me all that I needed. (Except that the upgrade broke some unrelated features anyway..)
