Yes, autoconf's configure wants recent versions of the automake macros,
so it includes its own copies (usually copied straight from CVS
automake), which are included from a manually maintained aclocal.m4.
This only imports them for use in _autoconf's_ configure script
though,not in all configure scripts generated by autoconf.  Only macros
from lib/autoconf/*.m4 are included in standard autoconf.
Basically, you should not be looking for available macros in the source
tree, but in the installed tree ($prefix/share/autoconf/) to be precise.
