I've tried to complile additional modules for as shared with the latest snap (18.10.2002) http://snaps.php.net/php4-latest.tar.gz and the operation failed - the same with php version 4.2.3 produces all chosen modules without any problems
here's what I've done:

./configure --with-apache=/usr/src/apache_1.3.27 --with-mysql=shared,/usr --enable-dba=shared --with-db3=/usr --with-gd=shared --with-zlib=shared,/usr --with-pcre-regex=shared --with-curl=shared,/usr --enable-bcmath=shared --enable-posix=shared  --enable-calendar=shared --enable-ctype=shared --enable-filepro=shared  --enable-shmop=shared  --enable-sysvsem=shared  --enable-sysvshm=shared --with-xml=shared  --enable-wddx=shared  --with-domxml=shared,/usr --enable-ftp=shared  --enable-sockets=shared   --enable-yp=shared  --enable-dbase=shared  --enable-exif=shared

and then:
make

and I've got this error:

without options:
--with-zlib=shared,/usr --with-pcre-regex=shared 
the whole thing compiles fine
