Description:
------------
i've been building/using php503 on OSX10.3.x for awhile with no problems.

after recently updating to php504 on OSX10.4.1, i can get a successful
build/install with my ususal cofig (shown below), EXCEPT for the inclusion of
an EXTERNAL pcre v50.

with a config of:

  ./configure \
  --disable-debug \
  --prefix=/usr/local/php5 --with-layout=PHP \
	--with-config-file-path=/var/Settings/PHP5 \
	--sysconfdir=/var/Settings/PHP5 \
	--with-pgsql=/usr/local/pgsql \
	--with-db4=/usr/local/berkeley-db \
	--with-mnogosearch=/usr/local/mnogosearch \
	--with-apxs2=/usr/local/apache2/sbin/apxs \
	--localstatedir=/var/Process \
	--mandir=/var/Documentation/man \
	--libdir=/usr/local/php_libs \
	--with-pear=/usr/local/php_libs \
  --enable-shared --disable-static \
  --enable-cli \
  --disable-cgi \
  --disable-dmalloc \
  --with-tsrm-pthreads \
  --enable-shmop --enable-sockets \
  --enable-inline-optimization \
  --enable-xml --enable-libxml --with-libxml-dir=/usr/local \
  --with-java=/Library/Java/Home \
  --with-openssl=/usr/local/ssl --with-openssl-dir=/usr/local/ssl \
  --with-zlib --with-zlib-dir=/usr/local \
  --with-imap=/usr/local/imap --enable-mailparse \
  --with-imap-ssl=/usr/local/ssl \
  --with-mcrypt --with-mhash=/usr/local \
  --without-gmp \
  --with-gettext=/usr/local \
  --with-gd=/usr/local/gd \
  --with-png-dir=/usr/local \
  --with-jpeg-dir=/usr/local \
  --with-tiff-dir=/usr/local \
  --enable-magic-quotes \
  --enable-calendar \
  --with-kerberos=/usr \
  --with-freetype-dir=/usr/X11R6 \
  --with-xpm-dir=/usr/X11R6 \
  --enable-exif \
  --enable-ftp \
  --enable-bcmath \
  --enable-mbstring \
  --enable-dio \
  --enable-session \
  --enable-soap \
  --without-snmp \
  --with-readline=/usr/local/lib \
  --without-cyrus \
  --with-pcre-regex


all's well & good.

but, with the SAME config, except for:

	...
	--with-pcre-regex=/usr/local/pcre50

'make' is still OK, but 'make install' fails with:

and subsequent attempts to install PEAR mods are met with the same 
preg_match
errors.

again, on OSX 10.3.9+php503, using external pcre-regex --> v50 was fine ...

there were some OLD discussions where these warnings/errors cropped up:

	http://bugs.php.net/bug.php?id=29914

and old bugs (e.g. #33334) where the advice was simply "use the bundled 
pcre" rather than to fix the problem ...

something clearly changed here ...
