Now that you mention it, I guess you are right.

I hate being able to think faster than I type:), I meant to say

Good point, I'm with you on this.

Well, with a single makefile, I don't think it will be possible to set
VPATH, since it can AFAIK only be set to one dir. Instead I think you
will have to do something like this for you compiling rules.

$(buildir)/path/in/svn/tree/%.o: $(srcdir)/path/in/svn/tree/%.c
        gcc -c -o $@ $<

(Now this can cause problems, because some compilers won't allow you
to specify both -c and -o (although autoconf should check this)). The
other problem is that you will probably now need a build rule for each
of the directories. Hmm... Needs more thought.
