PHP/Mapscript 4.6.0 build fails when PHP is DSO/--with-regex=php

Greetings, all:

First, some context:
I just got around to upgrading MapServer to 4.6.0 (from 4.4.1), and I'm
having a problem building the php_mapscript module. I'm running Slackware
Linux 10.0, Apache 1.3.33, and PHP 4.3.10. PHP was built from source with a
script that actually builds PHP twice: the first build creates an apache
DSO using --with-apxs=/usr/sbin/apxs and --with-regex=php (plus lots of
other configure switches, see below for the complete list); the second
build creates the CGI and CLI interpreters using --with-regex=system (plus
lots of others, see below).

Now my problem:
When I configure MapServer --with-php pointing to my PHP CGI/CLI build
directory, php_mapscript.so successfully compiles. However, when I
configure MapServer --with-php pointing to my PHP DSO build directory, the
MapServer build fails with compilation errors. The failing gcc command and
the corresponding error message appear as follows (I have saved the
complete log, if anyone would like to see it):

.... (and so on; snipped for brevity) ....

Strangely, the failure occurs while compiling regerror.c within the PHP
source tree. It is clear that the above error is caused by my PHP DSO
configuration, since my PHP CGI/CLI config works just fine with MapServer.
Any ideas what's going on here?

Additional details:
The following are complete listings of the ./configure switches I used to
build PHP and MapServer, just in case anyone wants to see them.

Here are the PHP configure switches common to both the DSO and CGI/CLI
builds:
  --prefix=/usr
  --sysconfdir=/etc
  --enable-discard-path
  --with-config-file-path=/etc/apache
  --enable-safe-mode
  --with-openssl
  --with-mhash
  --enable-bcmath
  --with-bz2
  --with-pic
  --enable-calendar
  --enable-ctype
  --with-gdbm
  --with-db3
  --enable-dbase
  --enable-ftp
  --with-iconv
  --with-exif
  --enable-exif
  --with-gd=/usr/local
  --with-jpeg-dir=/usr
  --with-png-dir=/usr
  --with-zlib-dir=/usr
  --with-freetype-dir=/usr/local
  --with-gmp
  --with-pgsql=/usr/local/pgsql
  --with-curl=/usr
  --with-mysql=shared,/usr
  --with-gettext=shared,/usr
  --with-expat-dir=/usr
  --with-xml
  --enable-wddx
  --with-mm=/usr
  --enable-trans-sid
  --enable-shmop
  --enable-sockets
  --enable-sysvsem
  --enable-sysvshm
  --enable-yp
  --enable-memory-limit
  --with-tsrm-pthreads
  --enable-shared
  --disable-debug
  --with-zlib=/usr

Here are the additional switches used specifically for the PHP DSO build:
  --disable-static
  --with-apxs=/usr/sbin/apxs
  --with-regex=php

Here are the additional switches used specifically for the PHP CGI/CLI
build:
  --enable-force-cgi-redirect
  --enable-fastcgi
  --enable-pcntl
  --enable-sigchild
  --with-regex=system

Finally, here are ./configure switches used to build php_mapscript.so for
use with DSO PHP (when building it for use with CGI PHP, only the last
switch is different):
  --with-gd=/usr/local
  --with-jpeg=/usr
  --with-freetype=/usr/local
  --with-zlib=/usr
  --with-png=/usr
  --without-tiff
  --without-eppl
  --with-proj=/usr/local
  --with-threads
  --with-gdal=/usr/local/bin/gdal-config
  --with-ogr
  --with-postgis=/usr/local/pgsql/bin/pg_config
  --with-wfs
  --with-wmsclient
  --with-wfsclient
  --with-curl-config=/usr/bin/curl-config
  --disable-ignore-missing-data
  --disable-debug
  --with-php=/usr/local/src/php/pkg_tmp/php-4.3.10-dso-build

Thanks,
