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:
autoupdate <file>

Some editors utilizing .editorconfig automatically trim whitespaces. For
convenience this patch removes whitespaces in certain build files:
- ext/*/config*.m4
- configure.ac
- acinclude.m4
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.
Once upon the time, commit c58f63a38a
changed the check from U8T_CANONICAL to U8T_DECOMPOSE. However,
the autoconf cache id was not renamed.
Sometimes it is desirable to preseed the autoconf variables, e.g. when
cross-compiling to avoid the tests running on the host system. In this
case it's confusing when the cache id does not match the variable to
set, so let's adjust it.

The test program for utf8_to_mutf7 attempts to call it without
arguments. The function expects one argument, however, and this leads
to a segfault as reported in PHP bug #66909.
The test program is using the PHP_IMAP_TEST_BUILD macro which
complicates things a little. To keep this diff small, the
PHP_IMAP_TEST_BUILD macro was modified to pass a fifth argument
"extra-source" to the PHP_TEST_BUILD macro. The check for
utf8_to_mutf7 was then modified to check for a dummy function,
utf8_to_mutf7_php, which passes the correct number of arguments to
utf8_to_mutf7.
