Quickly again (let's say that AC_CONFIG_MACRO_DIR([m4]) is specified):
a) Warn because 'aclocal -I m4' wants to search 'm4' dir which does not
exist. Ignoring this completely is imo idea;
b) Don't fail in that because it breaks autoreconf chain;
c) Create the 'm4' directory in by autoreconf which is not necessary - but
it silences the warning. (And it "fixes" this problem also, as the
automake does not have a reason to fail).
