Zack and all - Thien-Thi (cc'd) just reported two failures in automake make check with autoconf-2.69c (bugs.gnu.org/43819). The critical message appears to be:
./lib/autoconf/general.m4:2328: AC_DIAGNOSE is expanded from... /home/ttn/local/.b/automake-1.16.2/m4/init.m4:29: AM_INIT_AUTOMAKE is expanded from... configure.ac:2: the top level configure.ac:2: warning: The macro `AC_DIAGNOSE' is obsolete. Since AM_INIT_AUTOMAKE calls AC_DIAGNOSE, can you please not make it obsolete? Otherwise upgrading will be a nightmare for everyone. (Personally I'm skeptical that any longstanding macro should ever be declared obsolete. But anyway.) Thanks, Karl
