It is/was 48962. This is what i get with  svn up -r HEAD , even today.
I tried a bisection between last official release and HEAD and it
stopped at 48852;
BTW: the log message of 48852 shows someone has checked in in full
awareness of breaking something.
My suspicion: the set of available static variants of some libraries is
different on my Fedora 17/18 then on the actual developer machine.
For example: i have only the 64bit static libxml2-library no 32bit.

Not even a small text file with the last build number in root-directory?

This means, eventually the release tarball is patched and eventually not
existent in the SVN repository?

So another question: if my intention is to deliver a patch upstream is
it better to base it on SVN or on tarball?
( svn diff is a much simpler way to produce a patch )
