I can't thank you enough for taking the time to read that long post of 
mine /and/ reply with such a detailed and well-written explanation!
And of course you are correct, having the m4 macro expand the variable 
to $(srcdir)/tools/ (and, along the same lines, rewriting the 
build rule to refer to $(srcdir)/ solved that problem just 

About the quoting in the m4 macro: 

ac_foo2cpp="\$(srcdir)/tools/ ${ac_foo2cpp}"

was apparently the right way to do this.

It seems you replied off-list? Would you consider posting to the list 
what you wrote? Your explanation is definately worth archiving and I 
know for a fact that many of my fellow students will be having similar 
problems pretty soon.

If you don't want to I could forward your message or quote it in a 
follow-up or whatever.

Again, thank you very much! You spared me a lot of further trouble :)
