Because Autoconf is not M4!  Because such a large framework must make
provisions precisely so that the whole architecture work.  Ans esyscmd
is teh best example of what cannot be kept.

OK.  I agree that

is not clear enough, it seems to refer to M4sugar and M4sh only.  And

Sorry :)  I mean, when you clear hit a limitation of a tool,
contacting the developper of the tools will certainly provide a better
solution that doing something on your side.
