Description:
------------
Every time I try to compile PHP 5.1.4 with IMAP support under SLES9, it fails because of the wrong parameter count of utf8_mime2text() in php_imap.c:78 compared to utf8.h:538.
I have tried with imap-2004g.tar.Z and the current imap-2006.DEV.tar.Z.

Build c-client library first:
cd /usr/local/applications/
tar xzf imap-2006.DEV.tar.Z
mv imap-*/ imap/
make slx all SSLTYPE=none IP=4
md include
md lib
cp src/c-client/*.h include/
cp c-client/c-client.a lib/libc-client.a
cp c-client/osdep.h include/
cp c-client/env_unix.h include/
cp c-client/linkage.h include/


Reproduce code:
---------------
./configure --prefix=/usr/local/applications/lamp2/php --with-imap=/usr/local/applications/lamp2/imap --with-apxs2=/usr/local/applications/lamp2/httpd/bin/apxs --with-mysqli=/usr/local/applications/lamp2/mysql/bin/mysql_config --with-mysql=/usr/local/applications/lamp2/mysql --with-zlib-dir=/usr/lib/ --enable-versioning --enable-track-vars=yes --enable-url-includes --enable-sysvshm=yes --enable-sysvsem=yes --enable-ftp --enable-calendar --with-config-file-path=/usr/local/applications/lamp2/php --with-gd --with-xmlrpc --with-curl=/usr/local/applications/lamp2/curl --with-bz2 --enable-shmop --with-tidy=/usr/local/applications/lamp2/tidy --with-libxml-dir=/usr/local/applications/lamp2/libxml2 --with-openssl=/usr/local/applications/lamp2/openssl --with-ldap=/usr/local/applications/lamp2/openldap --with-pdo-sqlite --enable-pdo --enable-bcmath --enable-mbstring --with-xsl=/usr/local/applications/lamp2/libxsl --enable-shared --disable-static

Expected result:
----------------
Successful build (not aborted).


Only if I change line 538 in
/usr/local/applications/lamp2/imap/include/utf8.h
from
  long utf8_mime2text (SIZEDTEXT *src,SIZEDTEXT *dst,long flags);
to
  long utf8_mime2text (SIZEDTEXT *src,SIZEDTEXT *dst);
the build runs successfully.

Actual result:
--------------
/tmp/lamp2/sources/php/php-5.1.4/ext/imap/php_imap.c:78: error: conflicting types for `utf8_mime2text'
/usr/local/applications/lamp2/imap/include/utf8.h:538: error: previous declaration of `utf8_mime2text'
