This is a nice idea. (I am still new to autoconf/
automake, so some constructs are not that obvious
to me.)

The libraries to be built are managed using canonical
names, e.g.

        libmylib_a_SOURCES = foo.c bar.c

Following your suggestion I would introduce

        libmylib_alibdir = $(libdir)
        libmylib_a_LIBRARIES = libmylib.a

But for the primaries the '_' is a token delimiter.
A short test showed no problem. Do you expect any
problems here for a more complex Makefile.am?

This is my suggestion:

+  if (0 && $owner != VAR_AUTOMAKE && $type eq '+')
     {
       error $location, "$var must be set with `=' before using `+='";
     }

I know it is rude. Probably the user variables with a
default value != "" will not work as expected, if I got
the code correctly. Are there any other problems to be
expected by this patch? ("make check" reported just
the pluseq7.test.)
