for those errors I found:

The 1.14 release also introduces new (non-fatal) runtime warnings to
simplify the transition to Automake 2.0.  You are free to ignore such
warnings for now, but should address them before the transition to
Automake 2.0 (whose ETA is about one year from now, maybe more, so no
need to hurry yet).
