there are several cumulative fixes that can be added little by little,
but the next obvious one is to get rid of all of those references tio
$(srcdir) and replace that with a single use of "vpath."  once you do
that, a number of other cleanups become possible.

would you like me to submit the appropriate vpath-related patch?
