Hmm, putting variables in *_SOURCES is problematic as the dependency
tracking code in m4/depout.m4 is really dumb and may do the wrong thing.
$(top_srcdir) is certainly better than @top_srcdir@ here, but it may
even be that for correct functionality you need to just spell it out
with runs of "../".

This is fine.
