the known shells that are good enough to run the automake testsuite
do automatically exit with error when a sourced file cannot be found

that is, one using the setup code triggered by the first condition,
one using the setup code triggered by the second condition, and one
using both this setup code fragments.
Admittedly, this was only a theoretical limitation for the moment,
since since so far no test exists that matches two or more conditions
for wrapping. Still, this might change in the future, and easily in
an unnoticed way, so better fix the issue now, before it might become
a real problem.

compile: support libfoo.a naming when wrapping Microsoft tools
There is a future plan to provide some means to have Automake
create static libraries that are named differently depending
on the system [1].
The background is that everyone has always named static libraries
libfoo.a, except the Redmond crowd who names them foo.lib, and
you have to jump through hoops to have Automake create libraries
named foo.lib in the land of non-GNU Windows while still creating
libfoo.a everywhere else.
However, there is probably no sane way to accomplish that system
dependent naming discussed in [1] without user intervention,
which makes it necessary to support the classic libfoo.a naming
when using Microsoft tools in the best possible way, for the
benefit of all projects today and for future projects not
opting in to whatever scheme is selected for the problem at
hand.

libfoo.a, if that file exist on the library search path.

config headers: don't emit rules for headers not generated by autoheader
This change fixed automake bug#12495.
Even if an AC_CONFIG_HEADERS invocation is passed a list of several files
as the first argument, only the first one of those file is considered by
autoheader for automatic generation of the corresponding '.in' template.
This is done on purpose, and is clearly documented in the Autoconf manual,
which (as of the 2.69 version) reads something like this:
The autoheader program searches for the first invocation of
AC_CONFIG_HEADERS in configure sources to determine the name of
the template. If the first call of AC_CONFIG_HEADERS specifies
more than one input file name, autoheader uses the first one.
That is, an invocation like:
AC_CONFIG_HEADERS([config.h config2.h])
should cause autoheader to generate only a 'config.h.in' template,
and not also a 'config2.h.in' one.
Accordingly, automake, when tracing AC_CONFIG_HEADERS, should generate
remake rules only for the template associated to the first input file
name passed to that macro. In some situations, however, automake failed
to properly limit itself in this way; for example, with an input like:
AC_CONFIG_HEADERS([config.h sub/foo.h])
in configure.ac, and with the 'sub' directory listed in the SUBDIRS
variable of the top-level Makefile, automake would erroneously generate
in 'sub/Makefile.in' a rule to remake the 'foo.h.in' template by
invoking autoheader.
* NEWS: Update.

hat rules automake generates in response to an 'AC_CONFIG_HEADERS'

in here.

AM_INIT_AUTOMAKE: allow obsolescent two-args invocation once again
This partially reverts commit 'v1.12-67-ge186355' of 2012-05-25,
"init: obsolete usages of AM_INIT_AUTOMAKE not supported anymore"
Some users still need to be able to define the version number for
their package dynamically, at configure runtime.
Their user case is that, for development snapshots, they want to be
able to base the complete version of the package on the VCS revision
ID (mostly Git or Mercurial). They could of course do so by
specifying such version dynamically in their call to AC_INIT, as is
done by several GNU packages. But then they would need to regenerate
and re-run the configure script before each snapshot, which might be
very time-consuming for complex packages, to the point of slowing
down and even somewhat impeding development.
The situation should truly be solved in Autoconf, by allowing a way
to specify the version dynamically in a way that doesn't force the
configure script to be regenerated and re-run every time the package
version changes. But until Autoconf has been improved to allow
this, Automake will have to support the obsolescent two-arguments
invocation for AM_INIT_AUTOMAKE, to avoid regressing the suboptimal
but working solution for the use case described above.

On current OpenIndiana (based on what once was OpenSolaris 11), the shell
/bin/sh (which, differently from what happens on Solaris, is a true POSIX
shell, thus worthy of consideration) somehow manages to "eat" the
error message from 'rm' when that fails to remove a file due to lacking

That is probably due to an improper optimization, that is, the shell tries
to be smart and remove the file itself instead of invoking 'rm', but fails
spectacularly in the attempt.

failure in this test case. Cater to thus situation, by relaxing the

At least the AT&T and OpenSolaris versions of the Korn shell, as well
as the /bin/sh from OpenIndiana 11, have a strange bug regarding the
expansion of ${1+"$@"}: when exactly *one empty* argument is passed to
a script run by one of this shells, inside that script ${1+"$@"} will
expand to *nothing*, rather than to to the single empty string, as
one would expect (OTOH, $# will correctly expand to 1). This buggy
behaviour was causing a spurious failure in our testsuite (test 6 in
't/automake-cmdline.tap'). Work around it.
