Don't you understand? How could I possibly answer that quiz, since it's been 4 years
I use 2.69? You can't tell for sure just because there has been no complain: you can
only tell for sure if someone you 'trust' check with what ever version you'd like to
use.

I have no interest here, but if you do check and guarantee it works, I happy to
trust you.

It is exactly the point sorry.  Besides, when a package requires an earlier version
then the latest stable, which is the case for Guile-Clutter for example, then
developers should provide a guidance for users, on how to exactly locally install
earlier then stable versions in a way that it does not interfere with the rest of
the system.

Besides, 'users' who locally manually install and compile GDB probably know a lot
more then I on the subject :) And I bet they all setup a specific environment for
that..

If they do not have a specific environment, these advanced 'users' [you mean top
notch hackers right?] know they can locally edit our configure.ac file and try what
ever version of autoconf they have... It will most probably work, I agree with you,
but I'm not interested to try and offer guarantee...

Cheers,
