lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
Automake as follows:
* lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
`$configure_in' instead of `configure.in', to preserve
directory component.
sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
Warn about obsolete install-sh files. Remove stray sentence
fragment and fix cross reference.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
install -d; this undoes the 2006-05-10 change.
(MKDIR_P): Mark with AN_MAKEVAR.
(AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
that we don't require $INSTALL to be thread-safe. Move comments
out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
of AC_PROG_INSTALL. Output a message saying that we're checking
mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
MKDIR_P instead of AC_SUBST.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
Special magic for MKDIR_P, too.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
a dnl.
* tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.

* config/install-sh: Initialize IFS, so field splitting isn't
turned off later.
* config/mkinstalldirs: Likewise.
* config/missing: Remove superfluous quotes. Replace all uses of
`[' by `test', for consistency, and for..
* config/missing (sed_minuso, sed_output): New variables.
(autom4te, help2man, makeinfo): Use them. Unifies detection of
`-o FILE', `--output FILE', `--output=FILE', stricter regex.
Fixes `missing' to detect `--output' for help2man. Fixes
PR automake/483. Report by Dennis J. Linse.
(autom4te): Document in `missing --help'.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate POSIX 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-POSIX hosts.
Invoke mkdir at most once per dir arg on pre-POSIX hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
munge (multiple) white space and other oddities.
* tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
single quotes in variable assignment.
(AC_ARG_VAR, configure invocation): Adjust tests to expose this
and similar failures by adding multiple spaces, tabs, and other
special characters.
Report and different test suggested by Francesco Romani
<fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
single quotes, we only need to search for single quotes; this
both simplifies the search pattern, and makes us less
susceptible to `echo' variations for arguments not containing
single quotes.
(_AC_ARG_VAR_VALIDATE): Likewise.
traditional shells like the Solaris one that do not use the
first IFS character for assembling `$*'.
Prompted by a related report from autoconf_bug@nro.ca.
in URLs to improve DVI formatted output (requires texinfo 4.6).
(System Services, Systemology, Shellology): Likewise.
(Limitations of Usual Tools): Rewrite Mac OS X example for nicer
output.
(Integer Overflow, Null Pointers, Buffer Overruns):
(Floating Point Portability, Exiting Portably): New sections.
(Writing Test Programs): Fix some langauge. Recommend exiting
with status 1, not merely nonzero. Clarify exit declaration.
(Run Time): Move C exit status stuff to new Exiting Portably section.
(Systemology): Mention Posix and levenez. Update v7 reference.
(Portable Shell): Mention the Posix shell.
* doc/autoconf.texi (Programming in M4sh): Comment out the
documentation of AS_BASENAME, for now.
(Shell Substitutions): Do not use AS_DIRNAME in an example.
(Limitations of Builtins) <basename>: Do not refer to
AS_BASENAME.
* bin/autoconf.as (me): Don't use AS_BASENAME.
(dir): Remove the unused variable.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(AS_BASENAME): Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
(AS_DIRNAME): Use "dirname --".
of "run time" and "run-time" changed to "runtime", for consistency.
* lib/autoconf/fortran.m4: Likewise (in comment).
* lib/autoconf/functions.m4: Likewise.
* lib/autoconf/general.m4: Likewise.
* lib/autoconf/headers.m4: Likewise.
