Support for the two- and three-arguments invocation forms of the
AM_INIT_AUTOMAKE macro, as in:
AM_INIT_AUTOMAKE($PACKAGE, $VERSION)
or:
AM_INIT_AUTOMAKE($PACKAGE, $VERSION, NODEFINE)
will be removed in the next major Automake release (1.13).
Such usages have already been deprecated in the documentation
starting from commit
v1.11-2015-ge99690a of 23-02-2012 "docs,
news: document planned removal of obsolete macros and features".
We now start giving runtime warnings as well (in the 'obsolete'
category).
* NEWS: Update.
* m4/init.m4 (AM_INIT_AUTOMAKE): Report the two- and three-arguments
form invocation.
* automake.in (scan_autoconf_traces): Likewise.
* doc/automake.texi: Minor adjustments. Add an @anchor to the
location where it's described how to modernize outdated invocation
of AM_INIT_AUTOMAKE, so that it can be referenced from automake
warning/error messages.
* t/aminit-moreargs-deprecation.sh: New test.
* tests/list-of-tests.mk: Add it.
* tests/ac-output-old.tap: Adjust by calling automake with the
warnings in the 'obsolete' category disabled.
* t/backcompat.test: Likewise.
* t/backcompat3.test: Likewise.
* t/backcompat5.test: Likewise.
* t/backcompat6.test: Likewise.
* t/version.test: Likewise.
* t/version2.test: Likewise.
* t/pr2.test: Modernize style of AC_INIT and AM_INIT_AUTOMAKE
invocations, and use proper m4 quoting.
* t/pr87.test: Likewise.
* t/confsub.test: Likewise.
* t/install2.test: Likewise.

* Deprecated obsolescent features:
+ - Use of the long-deprecated two- and three-arguments invocation forms
+ of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
+ category. Starting from the next major Automake release (1.13), such
+ usages won't be allowed anymore.
+
- Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
now deprecated (its use triggers a warning in the 'obsolete' category).
It will be removed in the next major Automake release (1.13).

This macro can also be called in @emph{another, deprecated form} (support
-for which will be @emph{removed in the next major Automake release}):
+for which will be @emph{removed in the next major Automake release (1.13)}):
@code{AM_INIT_AUTOMAKE(PACKAGE, VERSION, [NO-DEFINE])}. In this form,
there are two required arguments: the package and the version number.
This form is obsolete because the @var{package} and @var{version} can
be obtained from Autoconf's @code{AC_INIT} macro (which itself has an
old and a new form).
