Not acceptable.  People are quite used to

Should be more explicit.  I currently have in configure.in

but this works only with autoconf 2.53.  Previously the diversion was
named AC_DIVERSION_INIT.  Do you have any good proposal of how I can
make this check for various names of a suitable diversion and then
use the one that is defined?  I am not good with m4 and its ilk.

I would like this to work for a few versions of autoconf at least,
and the name for a suitable diversion has changed over time.
