Description:
------------
When i try to compile with IMAP, it just thrown an error and say

error: utf8_mime2text() has old signature, but U8T_CANONICAL is present. This should not happen. Check config.log for additional information.

I am trying to use imap-2007f from source. I did make on imap-2007f before compiling PHP and imap relays on /usr/local/imap-2007f

I also tried imap-2007e.

And yes, libc-client and libc-client-devel is installed by RPM. But the version is 2007e. As i said both 2007e and 2007f gives the same exact error.

Here is the config.log -> http://www.mediafire.com/?1qpg27j7xd19l6o

I built PHP many times with the exact this configure parameters before. All of them on CentOS 5.8. I am getting this error on 6.3. Weird. Same parameters with centos 5.8 did the job.

Most weird thing is; If i only use --with-imap (without path) it gives me the same error.

Test script:
---------------
'./configure' '--build=x86_64-redhat-linux-gnu' '--host=x86_64-redhat-linux-gnu' '--target=x86_64-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' '--libdir=/usr/lib64' '--libexecdir=/usr/libexec' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--cache-file=../config.cache' '--with-libdir=lib64' '--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d' '--disable-debug' '--with-pic' '--disable-rpath' '--without-pear' '--with-bz2' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-xpm-dir=/usr' '--enable-gd-native-ttf' '--with-t1lib=/usr' '--without-gdbm' '--with-gettext' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-pcre-regex' '--with-zlib' '--with-layout=GNU' '--enable-exif' '--enable-ftp' '--enable-sockets' '--with-kerberos' '--enable-ucd-snmp-hack' '--enable-shmop' '--enable-calendar' '--with-libxml-dir=/usr' '--enable-libxml' '--with-xmlrpc' '--enable-xml' '--with-system-tzdata' '--with-mhash' '--with-mysql' '--with-gd' '--enable-dom' '--disable-dba' '--without-unixODBC--disable-xmlreader' '--disable-xmlwriter' '--without-sqlite' '--with-sqlite3' '--enable-phar' '--enable-fileinfo' '--enable-json' '--without-pspell' '--disable-wddx' '--disable-posix' '--disable-sysvmsg' '--disable-sysvshm' '--disable-sysvsem' '--enable-pdo' '--enable-mbstring' '--enable-fastcgi' '--with-mcrypt' '--enable-fpm' '--with-mysqli=mysqlnd' '--with-pdo-mysql=mysqlnd' '--enable-pcntl' '--with-imap=../imap-2007f' '--with-imap-ssl' '--with-pgsql=/usr/pgsql-9.2' '--with-pdo-pgsql=/usr/pgsql-9.2' '--with-curl=../curl-7.26.0'

Expected result:
----------------
PHP compiles as it did before on CentOS 5.8.

Actual result:
--------------
checking if your cpp allows macro usage in include lines... yes
checking for IMAP support... yes
checking for IMAP Kerberos support... yes
checking for IMAP SSL support... yes
checking for utf8_mime2text signature... (cached) old
checking for U8T_DECOMPOSE...
configure: error: utf8_mime2text() has old signature, but U8T_CANONICAL is present. This should not happen. Check config.log for additional information.
