Autoconf 2.59d (released in 2006) 1 started promoting several macros
as not relevant for newer systems anymore, including the AC_FUNC_VPRINTF.
This macro checks for presence of the vprint function otherwise checks
for presence of the _doprnt function. This check was relevant on very
old systems and today can be omitted since it should be well supported
by now. [2]
Also PHP doesn't use the HAVE_VPRINTF or HAVE_DOPRNT symbols.

- move relevant parts into win32
- general cleanup
- use Windows API and fallback to POSIX
- improve filetime to timestamp conversion
- improve stat/fsat
- handle ino by using file index
- handle st_dev by using volume serial number
The inode implementation is based on file indexes from NTFS. On 32-bit,
fake inodes are shown, that may lead to unexpeted results. 64-bit
implementation is most reliable.
Since Autoconf 2.50+ macro AC_STRUCT_ST_BLOCKS defines the new
HAVE_STRUCT_STAT_ST_BLOCKS symbol and has deprecated the previous
HAVE_ST_BLOCKS.
PHP 5.3 required Autoconf 2.13 (released in 1999) or newer, since PHP
5.4 the autoconf 2.59 (released in 2003) or newer was required, and
since PHP 7.2, autoconf 2.64 (released in 2008) or newer is required.
Attempting to create a symlink on Windows via the CLI SAPI without
administrative rights is likely to fail with ERROR_PRIVILEGE_NOT_HELD.
Therefore we map this Windows error to EACCES to get better diagnostics
and to avoid the assert() failure in debug mode.
These macros are supposed to behave like POSIX's symlink() and link(),
respectively, on POSIX compliant systems and on Windows.
Future scope: merge link.c and link_win32.c
Autoconf 2.50 released in 2001 has made several macros obsolete. Instead
of the AC_STRUCT_ST_BLKSIZE and AC_STRUCT_ST_RDEV the new
AC_CHECK_MEMBERS should be used.
When checking for the presence of stat struct members st_blkzize and
st_rdev the new AC_CHECK_MEMBERS macro defines new constants
HAVE_STRUCT_STAT_ST_BLKSIZE and HAVE_STRUCT_STAT_ST_RDEV.
Old constants HAVE_ST_BLKSIZE and HAVE_ST_RDEV need to be replaced
respectively in PHP code (this patch) and in PHP extenstions if they use
them.
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.
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.
The search path needs to be appended with the wild card. Till now, an
edge case existed, so then if a path is 259 bytes long, which is smaller
_MAX_PATH, the suffix would cause the final search path to become longer
than _MAX_PATH. It is an edge case, when the starting path happens to
have a specific length. If the starting path was longer than _MAX_PATH
or the addition of "\\*" would not exceed _MAX_PATH, the function was
correct. Except for rewind, which was broken in the case of the long
path.
The log header can be saved in the globals on startup. At the same
time, the log header can be changed per request. In case that
happened, wrong pointer will be free'd on shutdown. It can happen at
any point when zend_error() or similar is called at startup, like for
example in the case of the ini deprecation warnings. Thus, ZMM cannot
be used here.
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.
