Re: [GNU Autoconf 2.69] testsuite: 203 264 271 286 311 312 313 314 315 316 323 328 339 503 failed

A quick look at the first couple of failures indicates that they were fixed by 
patches to Autoconf that were installed after 2.69b came out, in particular:

If you can build Autoconf from Git master I suggest doing that; otherwise you 
can try waiting for the next beta or full release.
