We looked at a PHP package and its diversion usage for its toplevel
configure script with Autoconf 2.13 when a bug with PHP and newer
Autoconf was last reported, within the last couple of weeks, on the
bug-autoconf list IIRC, and when it was first reported, several months
ago.  What I could find there was that removing the diverts was mostly
a no-op (except for configure line numbers changing, and some comments).

But I haven't looked at the exact PHP version discussed in this thread
now.
