yes, if an autotools related file was touched. Cannot remember that it
happened otherwise. It can be avoided using the macro AM_MAINTAINER_MODE
which disables the so called "rebuild rules" by default but I don't
like it.

But this becomes off-topic and autotools stuff is indeed very

No, sorry I didn't investigated it yet as I wanted to start with a more
simple bug. (The problem is at least reported in the link mentioned

To be honest the build system never worked for me as user flawlessly
since years. For most of my problems I found solutions or workarounds
via Internet search so I assumed you know about these.

Here I think again that the rule not to create bug reports if not
aggreed on this list is not optimal. But now I'm at a state where I'm
familiar enough with the development of Subversion to provide patches
for hacking.html ...

And all others too? It's strange that nobody had any opinion about
a build error. This one was sufficient simple so that I thougth it would
be optimal for starting contributing but I lost the interest without

Maybe my email writing style wasn't good enough (no PATCH: tag, not

The solution could be a simple extension of the default targets by
sub-targets. Haven't tested it though.
