Instead of the project macro, the sockaddr_storage and sockaddr.sa_len
can be checked with the AC_CHECK_TYPES and AC_CHECK_MEMBERS by including
the sys/socket.h. Some systems (~1988) didn't include the sys/types.h in
the socket.h (obsolete on current systems).
These macros by default define the HAVE_STRUCT_SOCKADDR_STORAGE and
HAVE_STRUCT_SOCKADDR_SA_LEN.
The struct flock is defined in fcntl.h, if system has it. This removes
redundant PHP_STRUCT_FLOCK M4 macro in favor of the AC_CHECK_TYPES,
which by default defines symbol HAVE_STRUCT_FLOCK.
PHP_DEFINE was introduced with the PHP 5 build system
9d9d39a0de and then refactored via
350de12bc2.
This was once used to put defined constants into a single file to have
more fine-graned dependencies (atomic includes). Since no known PHP
extension is using this and it makes very little sense to use this, this
M4 macro can be removed in favor of the Autoconf native way using
AC_DEFINE and the usual included files php_config.h and config.h.
- Generated unused include directory removed
- Remove include dir from DEFS
- Remove also include dir from PDO checks
SunOS 4.1.4 from 1994 didn't have fclose declared in standard header
stdio.h. This doesn't need to be checked anymore, as fclose is part of
the C89+ standard and declaration is present on Solaris 10 (SunOS 5.10)
and later.
Global --tag=CC defined in configure.ac is not correct in all cases. For example
linking objects that were compiled from C++ sources needs to be done with C++
compiler, however for link mode libtool will prefer compiler indicated with
--tag.
Fixes GH-12349
The root library was added here for the Haiku system, to check dlopen()
and dlsym(). However, the root library is already explicitly linked in
the system, and it does not need to be checked neither linked anymore,
since at least ~2013.
The fastcgi code was refactored in
18cf4e0a8a and in_addr_t is no longer
used. The PHP_CHECK_IN_ADDR_T is also obsolete and not recommended way
to discover availability of the type. If needed in the future, the
AC_CHECK_TYPES can be used instead.
Autotools emits warning if 3rd argument is empty. Call is wrapped in the
AC_CACHE_CHECK with php_cv_* cache variable name according to the docs.
Closes GH-12966
While __php_mempcpy is only used by ext/standard/crypt_sha*, the
mempcpy "pattern" is used everywhere.
This commit removes __php_mempcpy, adds zend_mempcpy and transforms
open-coded parts into function calls.
This was disabled in 2019 due to problems reported in FreeBSD 11. The original
report (PHP bug 77284) includes a comment that FreeBSD 12 worked - which also
happens to be the first version ifunc use appeared in libc.

The macro checks for existence of size_t in <stddef.h> otherwise it sets
it to 'unsigned int'. The size_t is part of C89 standard and all
platforms should have it. Macro is also marked to be made obsolete in
the future versions of Autoconf.
At this point there is still AC_FUNC_ALLOCA in PHP's configure.ac which
uses AC_TYPE_SIZE_T under the hood so the check is still done there in
the meantime.
- AC_CHECK_HEADERS already includes the header(s) listed in the first
argument, so additional net/if.h is redundant.
- The crypt.h is checked two times and HAVE_CRYPT_H is only needed in
ext/standard.
- Remove duplicate <string.h> in ext/standard
- Remove duplicate <string.h> in getaddrinfo check in configure.ac
- Unused header checks removed:
HAVE_NETINET_TCP_H and HAVE_SYS_UN_H are not used in the code.
- Duplicate linux/filter.h check removed:
HAVE_LINUX_FILTER_H is already defined in ext/sockets.
clang and newer gcc releases support byte-sized atomic accesses on
riscv64 through inline builtins. In both cases the hard dependency on
libatomic added by GH-11321 isn't useful.
Stop using AC_CHECK_LIB() which is too naive to notice that libatomic
isn't needed. Instead, PHP_CHECK_FUNC() will retry the check with -latomic
if required.
Closes GH-11790
