You are right.  I did not develop my thought to its end :(

I guess I was afraid people would story macros in this directory,
instead of putting the file in the proper place.  I guess we now have
a good reason for introducing and promoting AC_INCLUDE: it is

Also, I read AC_MACRO_PATH as meaning `autoconf path', not `Autoconf
path', in other words, I'm facing a problem that gets more and more
frequent in Autoconf: the clash between the name of the package,
Autoconf, and that of one its tools, autoconf :(

Then, I think AC_MACRO_PATH should be AUTOM4TE_PATH, and the
documentation should emphasize that m4_include should include a prefix
part, autoconf/, autotest/ and so forth.  You are absolutely right: I
had you write support for something that should not exist.

Will you handle this?  Do you want me to face my responsibilities and
handle it?
