Autoconf problem with patch level 1.5.18

[Alexandre et/ou Sophie Beneteau]

Hi again !

I've try to compil lilypond 1.5.18 (by patching from 1.5.{15,16,17}) ; 
doing autoconf produce this error output :

1026:root:/usr/src/lilypond# autoconf
./aclocal.m4:999: error: m4_defn: undefined macro: _m4_divert_diversion
acgeneral.m4:1478: AC_ARG_WITH is expanded from...
./aclocal.m4:999: the top level

Autoconf version :

autoconf --version
autoconf (GNU Autoconf) 2.52
