Ticket #64712: config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU help2man configure 1.49.1, which was
generated by GNU Autoconf 2.71.  Invocation command line was

  $ ./configure --prefix=/opt/local --enable-nls
