The complete file is 1 MB, so probably not advisable to send this to the
list. I don't know how to give a good summary; below is the flat profile
cut off at function with some 0.05 % of the total time. If you are
interested in the call graph as well, its probably best if I send you
gzip of the complete file privately.
(Probably there are more intelligent ways to sort the information using
gprof, but 3 days ago I did not even know this program.)
It seems to me that one could save maybe 1 or 2 % by some 50 lines of code
with a specialized "count_approxlib" function, as approxlib is mainly called
from order_moves in reading.c, where the location of the liberties is
not used.

P.S.: This from the nngs test suite (with --experimental-influence, without
my patch). In a real game, influence functions probably need more time, as
the owl can then benefit from the persistent reading cache.
