I'd do the first rather than this:


Rationale: the user may want to invoke some other Libtool-related macros
right before and after AC_PROG_LIBTOOL, or use the new LT_INIT notation.

No, that sounds rather awful.

FYI, if you're out to use the libtool script from within configure, then
for CVS HEAD Libtool you need to put the LT_OUTPUT macro.  It isn't
defined nor necessary with 1.5.x.  I think you should be able to
  m4_ifdef([LT_OUTPUT], [AC_REQUIRE([LT_OUTPUT])])
