Tag builds from git

[Geert Janssens]

I have been stabbing at the tag build script today to get it working in 
a git context. There were some silly typos to fix, I had to restart a 
build because of a network glitch at the wrong time,... This is a slow 
and frustrating process, because the tag builds typically run for hours.

Anyway. The last tag build failed while configuring gnucash. I don't 
think this has anything to do with my git modifications though, so I'd 
like some input on what could be the problem. The log of the last build 
can be found here:
http://code.gnucash.org/builds/win32/build-logs/build-2.4.11-2012-08-16.log

The last part is this:

or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.

I'm not good at autotools, so perhaps someone can interpret this for me ?

This build started from a cloned git repository in which tag 2.4.11 was 
checked out (which for git is equivalent to svn rev 22265 on the 2.4 
branch).
