This is ok, but...

...this now have the wrong indentation: it should be aligned with the
opening '(' in the line above (so, basically, you have to kill one
white space and move it back by one column).

libxc functions are supposed to, on failure, set errno and alwas return
-1. Using LOGEV and passing r to it means that you're always logging -1
as error code.
I think 'LOG(ERROR, "blabla")' is what should be used here.
And these same comments apply to all the other hunks of the patch.

Dario
