Neither does it for me, actually using Cygwin (current, on Win10 
current).  And FWIW, the automake version that resolves to is 1.16.1, 
and autoconf is 2.69.

I didn't apply any fancy extra options to the git clone as in the 
original report, though; just plain git pull <address> into a fresh 
subdir under my cygwin-controlled /home/... (to make sure permissions 
and stuff were sane).

I had no warnings at all.  ./bootstrap && ./configure && make just worked:

$ ./ct-ng version
This is crosstool-NG version 1.24.0.479_aa52493
