Log message:
        * m4sugar.m4 (m4_undefine, m4_popdef): Don't tolerate undefined
        arguments.
        (_m4_expansion_stack): Rename as...
        (m4_expansion_stack): this, and change its value: instead of using
        the pushdef stack to stack each *line* of the stack, each
        definition contains the whole stack.  I.e., to display the whole
        stack, instead of popdefing and displaying each definition, just
        display the current definition.
        (m4_expansion_stack_push, m4_expansion_stack_pop): New.
        * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Let $2 be the expected
        exit status.
        * tests/m4sugar.m4 (m4_require: circular dependencies): New test.
