commit 8a349dccfad742966af8eaf551732bb4c84376dd
Author: Greg Hudson <ghudson at mit.edu>

    Rename configure.in to configure.ac
    
    autotools plans to drop support for the name configure.in.
    (automake's NEWS file expresses plans to drop support for it in
    autoconf 2.0; autoconf added a warning in commit
    560f16b52d3d3db1536d9ca5b863ce9b1a5c9e35, indicating in the commit
    message that support will be dropped in a future version.)
    
    ticket: 8788 (new)
