compat: substitute '@mkdir_p@' as '$(MKDIR_P)' unconditionally
We had started to do so only when the obsolete AM_PROG_MKDIR_P variable
was used, but that has recently turned out not to be not good enough,
because Gettext 0.18.2 (the latest one at the moment of writing) is using
the modern macro AC_PROG_MKDIR_P in its '*.m4' files, but at the same time
is still using the obsolete make variable '$(mkdir_p)' in its Makefile
fragments. This has been causing failures in real-world packages
bootstrapped with latest Gettext (0.18.2) and with bleeding-edge automake.
And the worst things is that those failures have been basically silent
and unnoticeable up until the final "make install" --- that is, after
the affected package had been bootstrapped, configured and built. Yikes!
This issue has been reported to the Gettext developers:
But even if they will quickly fix it, Gettext 0.18.2 will remain
affected.
The fix we can implement in Automake is small and unobtrusive enough,
definitely worth having in order to save the users and developers from
having to deal with this hard-to-spot issue.

tar: format 'ustar' cannot support UID/GID longer than 21 bits
See automake bug#8343 and bug#13588.
POSIX 1988 'ustar' format is defined with *fixed-size* fields. There
is notably a 21 bits limit (2097151) for the UID and the GID.
Tom Rini tom_rini@mentor.com says (in bug#8343):
When the user has a UID or GID that is larger than the ustar format
supports, pax does not error out gracefully in some cases (FC13).
Marc Herbert <marc.herbert@intel.com> adds (in bug#8343):
When "configure" is run by a user with an UID bigger than 21 bits,
BSD pax 3.4 aborts when trying to create the 'conftest.tar' test
archive and leaves an empty or corrupted conftest.tar file behind.
In the next step, pax tries to extract this incomplete or corrupted
archive and this *** hangs the whole ./configure script ***.
Note: GNU cpio 2.9 pretends to pass the test but it is a LIE: it
silently truncates any big UID to its lower 21 bits. I don't know
what can be the consequences of this lie.
I think there is currently a design issue in automake/m4/tar.m4
considering that a ustar archive should should *never* succeed when
./configure is run from a big user ID.
Months later, Petr Hracek <phracek@redhat.com> reports a similar issue
(in bug#13588) for Fedora 17:
I am trying to solve problem in case a user is created with big
UID and during configuration pax hangs with message
ATTENTION! pax archive volume change required.
Ready for archive volume: 1
Input archive name or "." to quit pax.

different from that original proposition, though.

Since INCLUDES and AM_CPPFLAGS can be both used at the same time in a

INCLUDES is, unfortunately, not simply a matter of doing a mindless
INCLUDES -> AM_CPPFLAGS substitution. In fact, the transition from a

subtle bugs to sneak into the build systems of the client packages
doing the transition. Forcing this risk upon our users is definitely
not worth the small enhancement in consistency and cleanliness that

perl: perl subroutine prototypes are problematic, don't use them
Basically, in perl, "subroutine prototypes" are not prototypes at all;
rather, they are a trick to allow user-defined subroutines that behave
like perl built-in functions. For example, prototyped subroutines can
be called without parentheses, and can impose context on their arguments.
Such semantics can be useful in some selected situations, but might also
easily cause unexpected and harmful behaviours and side effects if we
try to use perl prototypes as we would use C prototypes.
See the excellent article "Far More than Everything You've Ever Wanted
to Know about Prototypes in Perl" by Tom Christiansen for more detailed
information:
It is important to note that modern perl allows a non-predeclared
subroutine to be called without the '&' character, as long as its
call uses proper parentheses:
foo 'str', 2; # will trigger errors if foo is not predeclared
foo('str', 2); # ok even if foo is not predeclared
&foo('str', 2); # ditto; but the '&' is old-style and redundant
Note also that the prototype indicating "no argument":
sub func() { ... }
can actually be useful, and has no discernible downsides, so we'll
keep using it where it makes sense.
Also, in few, selected cases, we *want* to have subroutines behave like
perl builtins (e.g., we want the 'append_exeext' function to be able
to take a code block as first argument). In such cases, we will of
course continue to make use of perl subroutine prototypes.
Let's finally see an example that might clarify the kind of problems the
use of subroutine prototypes in perl can cause. This is just scratching
the surface; there are several other aspects, typically subtler and more
dangerous, that are not touched here.
If you have the prototyped subroutine definition:
sub foo ($@)
{
my $s = shift;
print "SCALAR: $s\n";
print "ARRAY: @_\n";
}
and call 'foo' in code like:
@list = (-1, 0, 1);
foo(@list);
you won't get a compile-time nor a runtime error (as a naive interpretation
of the "prototype" characterization would let you think). Rather, the
prototype will cause the array '@list' will be coerced into scalar context
before being passed too 'foo', which means that its *length* (3) will be
passed to 'foo' as first argument; and since no further arguments are
present after '@list', that *void* will be coerced to an empty list before
being passed to 'foo'.
So code above will have the result of printing:
SCALAR: 3
ARRAY:
Quite tricky, and definitely a behaviour we don't want to rely on.

remaining ones. Related minor simplifications and adjustments.

aclocal: just warn if the primary local m4 dir doesn't exist (don't error)
Related to automake bug#13514.
Every package which does not need to have the local m4 macro
directory pre-existing in the version control system (because
e.g., it does not have nor need any private m4 macros) would
fail during the "autoreconf -vfi" phase if AC_CONFIG_MACRO_DIRS([m4])
is specified in configure.ac (it could be to instruct tools like
'autopoint' and 'libtoolize' to use 'm4' as the local directory
where to install definitions of their m4 macros, and to instruct
aclocal to look into it). The failure would go like this:
autoreconf: Entering directory `.'
autoreconf: running: aclocal --force
aclocal: error: couldn't open directory 'm4': No such file or directory
autoreconf: aclocal failed with exit status: 1
The problem is that when 'aclocal' is run for the first time during
'autoreconf', the directory 'm4' does not exist yet. It will be
created by e.g., 'libtoolize' or 'autopoint' later on. During the
second 'aclocal' run, the 'm4' directory exists and aclocal does not
complain.
To work around this issue, we degrade the error to a simple warning.
The warning is still quite useful when aclocal is run by hand - so
we are not removing completely.

See discussion about automake bug#13578 for more details and background.
Basically, for the versioning scheme:
- micro versions only for bug and regression fixing;
- minor versions for new backward-compatible features, and new
non-fatal deprecations;
- major versions for backward-incompatibilities, complex new
features, and major refactoring.
And for the git branching scheme:
+ branch 'next' is for the upcoming major version;
+ branch 'master' is now for the upcoming minor version;
+ branch 'maint' is for the upcoming micro (bug-fixing) version;
+ the merging hierarchy is: 'maint' -> 'master' -> 'next'.

preproc: add support for relative names in included fragments
The rationale for this change is that it is annoying to have
to repeat the directory name when including a Makefile fragment.
For deep directory structures these repeats can generate a lot
of bloat. It also hinders reuse and easy directory restructuring
if all Makefile fragments have to know exactly where they live.
Suggested by Bob Friesenhahn, and later discussed in bug#13524.
In the course of discussion, the following notations were rejected:
&{reldir}& - to hard to type, {reldir} - interferes with ${reldir},
{am_reldir} - short form {D} interferes with ${D}, @am_reldir@ - short
form @D@ interferes with AC_SUBST([D]) as well as invading the
config.status turf. Other notations were also suggested...
* automake.in (read_am_file): Add third argument specifying the
relative directory of this Makefile fragment compared to the
main Makefile. Replace %reldir% and %canon_reldir% in the
fragment with this relative directory (with slashes etc, or
canonicalized).
(read_main_am_file): Adjust.
* t/preproc-reldir.sh: New test.
* t/list-of-tests.mk: Augment.
* doc/automake.texi (Include): Document the new feature.
NEWS: Add new feature.
tests on TAP: don't run the driver with perl unconditionally
* t/ax/tap-setup.sh: When a 'Makefile.am' was pre-existent in the
test directory at the moment the client test script sourced this
file, said 'Makefile.am' was tweaked to provide it with a proper
definition of TEST_LOG_DRIVER. However, there was an error in this
automatic definition, since it caused the TAP test driver to be
unconditionally invoked with perl. This wasn't an issue in most
situations, since perl is smart enough to re-execute a given script
with the proper interpreter if it sees a she-bang line that doesn't
seem to point to perl itself. Still, there is no reason to do
something blatantly wrong even if our tools correct the dumb mistake
for us. So fix the TEST_LOG_DRIVER definition.
maint: use more perl subroutines prototypes in the automake script
* automake.in: Throughout this file. Note that these new prototypes
are not much useful, since many subroutine calls still use the old
'&foo' form; but we'll take care of that in later patches.
* lib/Automake/Language.pm (target_hook): Call the '_target_hook'
of the given language in a more modern form, avoiding '&'.
build: auto-generate perl subroutines prototypes for automake and aclocal
This will allow us to avoid either using the '&foo' invocation form when
invoking a subroutine before its definition, or having to maintain the
list of prototypes by hand (with the risk of having it become incomplete
or fall out-of-sync when future edits to the automake and aclocal scripts
are done).
* Makefile.am (automake, aclocal): Automatically generate a list of
prototypes by looking at the subroutines definitions.
* bootstrap.sh: Likewise, when generating the temporary automake and
aclocal scripts used for bootstrapping.
* automake.in: Add a placeholder that will be tracked by the new recipes

that are now superfluous. Some adjustments required by the new, more
comprehensive prototypes declarations.

work, at least until the compiler is supported by Autoconf.
So there is no point in alarming our users by stating in the NEWS file
that "support for IRIX and the SGI compilers has been removed"; after
all, while we don't test on nor particularly care about IRIX anymore,
that doesn't mean we are deliberately breaking it, and the likelihood
of an intended breakage there is very low.
