The `mkdep.awk` file was part of the previous *nix build system and was
used to create a .deps file with a list of dependencies that could be
processed by Automake further on.
Newer build system was done via 9d9d39a0de
and outdated files removed via 22815419f8
so the current file in the PHP source code is not used anymore.
Additionally, the *.slo files were processed by this file. The *.slo
files also used to be generated by older libtool so today, these don't
get generated anymore.
The `makefile_am_files` was part of the previous build system where
automake was used to build Makefiles. Since 9d9d39a0de
this is not used anymore and can be removed.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

This patch syncs and bumps the minimum required version of Autoconf for
the `phpize.m4` script and the main `configure.ac` from previously mixed
2.64 and 2.59 to 2.68.
At the time of this writing Autoconf 2.63 is still the version on
Centos 6, however by the PHP 7.3 release current systems out there
should all have pretty much updated Autoconf versions to 2.64+ at
least. Centos 7 already has Autoconf 2.69, for example.
This provides more options to update and get current with the *nix
build system and also avoids broken builds in certain cases as pointed
out in the relevant discussion [1].
Additionally, phpize also already provides the `AX_CHECK_COMPILE_FLAG`
Autoconf Archive m4 file that has Autoconf 2.64 minimum requirement.
Autoconf 2.68 was released in 2010, 8 years ago, relative to this patch.

ICU 59 already requires C++11 by default. The minimum version required
by the core is 50, which is compiled with at least C++11 in many distros
as package defs tell. Headers for ICU versions between ICU 50 and 58 look
fine when included for C++11 compilation, the linking is thereof not affected.
The macro PHP_CXX_COMPILE_STDCXX is based on
https://www.gnu.org/software/autoconf-archive/ax_cxx_compile_stdcxx.html
The patch consists on allowing to read the corresponding switch in a user
defined variable instead of enforcing CXXFLAGS globally. That way, every
ext or SAPI can decide, which C++ standard is to be used. The
documentation is provided in the m4 file.
C++11 is already somewhat older standard, C++14 were better. However
issues with GCC < 5.0 and some other compilers are possibly to hit back.
Still there's some time to check for C++14 for ext/intl, too. Having said
that, C++11 in ext/intl and a mechanism to determine features is a good step
towards better C++ support.
This patch makes several scripts and PHP development tools files
executable and adds more proper shebangs to the PHP scripts.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`.
Autoconf 2.50 released in 2001 made several macros obsolete including
the AC_TRY_RUN, AC_TRY_COMPILE and AC_TRY_LINK:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2
These macros should be replaced with the current AC_FOO_IFELSE instead:
- AC_TRY_RUN with AC_RUN_IFELSE and AC_LANG_SOURCE
- AC_TRY_LINK with AC_LINK_IFELSE and AC_LANG_PROGRAM
- AC_TRY_COMPILE with AC_COMPILE_IFELSE and AC_LANG_PROGRAM
PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version therefore systems
should be well supported by now.
This patch was created with the help of autoupdate script:

Since PHP 5.3 flex lexer has been replaced with re2c. Commit
0f9e2b1753 made PHP_PROG_LEX macro still
available for BC.
In commit df6bd506d4 it was updated. Since
this macro is entirely not used in PHP source code anymore from PHP 5.3
and up, this patch removes it together with some old traces of warnings
suppression and comments.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
When the PHP source code was versioned in Subversion, there was
possible to substitute certain keywords such as $Id$ with revision
number, last change time and author name. Such approach is not used
in Git so this patch removes these outdated artifacts from source
code files.
configure.ac was introduced in 2001 with automake-1.15 and autoconf-2.50
to replace the file named configure.in.
Autotools is preparing to remove configure.in in Automake 2.0.
All new software should be using configure.ac.
This also fixes Bug #69770 where extensions are creating configure.in
