Warning: I'm going to give the "AM_MAINTAINER_MODE is pure evil
on a stick" point of view. I know some people find it useful
(although I don't know when).

*Testing* for these tools will not break your build.
Now there are three cases:
1. The user unpacked your package, and then run ./configure and make.
Since all the configury files (configure, Makefile.in, config.h, etc.)
are up-to-date w.r.t. their sources (configure.ac, Makefile.am, etc.)
there is no need to rerun any of the auto* tools.
So you checked for those tools but whether you find them or not
isn't important since they are not used. This is the most
common "user" case.
2. The user modified configure.ac, or Makefile.am, or a sibling.
Obviously something needs to be regenerated to reflect these changes.
Automake has added rules for this purpose in the Makefiles; these
rules use the auto* tools found by configure. If these tools
was not found, the "missing" script prints an error message so
the user understand he needs them.
3. Your package is broken, it contains some files which are
out-of-date w.r.t. their source. The user then get "missing"
errors when they try to build. He reports them to you,
and you fix your package. (I don't think it can happen
if you use 'make distcheck'.)
Let's see what happens when AM_MAINTAINER_MODE is used:
1. Just the same.
2. Running `make' after changing something doesn't update the
dependencies. The user has to _know_ he should
--enable-maintainer-mode, otherwise he will wonder why his
changes have no effect (or worse: he won't notice they
wasn't taken into account).
3. Although the package is broken (for instance configure
doesn't reflect the content of configure.ac), the build will
start anyway because the bug is *hidden*, and it may fail
latter because of this non obvious configure/configure.ac
mismatch.
In the common case (1.) using AM_MAINTAINER_MODE changes
nothing, in less usual cases (2., 3.) it just hides bugs when
you forget to type --enable-maintainer-mode.
(If you search the web for discussion about AM_MAINTAINER_MODE
you will find some worth-reading rants from François Pinard on
this topic, with some more philosophical points -- I'm sorry I
don't have any pointer handy.)
As far incompatibilities between different versions of these
tools are concerned, this is unrelated to AM_MAINTAINER_MODE.
If you have changed some source, you need the right tool to
rebuilt it (and obviously you want the maintainer rules too).
If however you touched nothing, you don't care about which
versions you have.
