I used 2.60 to regenerate in newlib/, was that the wrong thing to do?

/usr/build/src-winsup/newlib $ head -3 configure
#! /bin/sh
# Guess values for system-dependent variables and create Makefiles.

That would be the freshly regenerated one:

/usr/build/src-winsup/newlib $ head -1 aclocal.m4
# generated automatically by aclocal 1.9.6 -*- Autoconf -*-
