Hi Stepan,
Again I'll only refer to part of your well-written mail, not because of
ignorance but because this issue is more important to me at the moment,
and I will come back later to the other one:

Well, for CVS HEAD Libtool, it would be very nice to be able to say
# LT_INIT([OPTIONS])
# ------------------
AC_DEFUN([LT_INIT],
[m4_require([_LT_SET_OPTIONS], [_LT_SET_OPTIONS([$1])])[]dnl
# ...
])
# _LT_SET_OPTIONS([OPTIONS])
# --------------------------
m4_defun([_LT_SET_OPTIONS],
[m4_foreach([_LT_Option], m4_split(m4_normalize([$1])),
[...])
# ...
])
Would this be allowed? If not, what can we do instead
(_LT_SET_OPTIONS will only be called once)?

This is a very dangerous "conclusion". Most of the questions I ask are
motivated by the desire to mimimize Libtool maintenance costs.
I can tell you about one other project I am looking at a bit at the
moment[1], and trying to work around Autoconf-2.59 within a configure.in
written for 2.13 causes major pain. Luckily most of that project has
been converted to use the most recent stable autotools.

See above, such a thing would be "very nice to have".
Cheers,
Ralf
