With my modifications to libxc(adding/modifying a few files), I get
the following error, but only intermittently. There are no compilation
errors in my code. And, also interestingly when I add back the same
changes piece-meal and in a different order, this linker error
disappears. What could be the reason ?

Also, "make clean" doesn't help either. The error goes away only on a
(trial and error) reordering of my patch set.

Never mind ! Figured it out. One of my files should go to libxenguest.
