The versions Jeff and I use for newlib are
aclocal-1.11.6 -I. -I.. -I ../.. -I ../../..
autoconf-2.68
automake-1.11.6 --cygnus --no-force
The problem is to revamp the newlib tree to do the right thing without
the dreaded --cygnus option. In the meantime we are using the latest
automake/autoconf tools at least in the Cygwin part of the repo, thanks
to Jon Turney.
