Hi Eric,

And that's, as you guessed, the culprit. As I'm working on a downloaded
tarball, there is no svn repo information so 'svn info' returns nothing.

No svn info and all the following m4_defines using SVNINFO return nothing.
My solution was to simply hardcode all the vars depending on the svn info
using the info that svn returns for that release branch.

Yes, but I don't intend to mess much with the m4/autoconf stuff beyond this.
But thank you for helping me to understand that stuff enough to make it
work. It's really appreciated! And thanks for the tip on debugging helps,
I'll keep them in mind.
