I wrote an answer yesterday, but by mistake I posted it to Ralf only.
In short, I'm not sure that the feature is necessary.

Ralf wrote me a very nice explanation, which convinced me.
In short, it is needed as the solution for PR/477.

Perhaps you could post the explanation here, Ralf?

I still think it should be implemented in Autoconf, see the patch below.

Would you like it this way?  If yes, I'll finish the patch and submit it
to autoconf-patches.

(A nice side effect: AC_SUBST_NOTRACE would work even if used with
previous versions of Automake.)

Have a nice day,
