 - from my understanding the old autoconf won't touch configure.ac and
 the new one won't touch configure.in. So I see no reason why
 configure.in should be renamed to configure.old.
 - running it here produce:
$ ./autogen.sh
+ checking for autoconf >= 2.52 ... + checking for autoconf >= 2.13 ... found 
2.13, ok.
+ checking for automake >= 1.4 ... found 1.4, ok.
+ checking for xgettext >= 0.10.38 ... found 0.10.39, ok.
+ checking for msgfmt >= 0.10.38 ... found 0.10.39, ok.

  The first line is ugly.
 - It produce warnings:
+ running autoheader ...
configure.in:360: warning: AC_TRY_RUN called without default to allow cross 
compiling
+ running autoconf ...
configure.in:360: warning: AC_TRY_RUN called without default to allow cross 
compiling
+ running automake ...

 This is probably because of the changes in m4/x.m4. What about two
 files (m4/x-ac213.m4 and m4/x-ac25.m4) or two directories (m4-ac213
 and m4-ac25) (but these two dirs seems like overkill)?
