I'm unable to link libphp4.la using --with-openssl. I'm using:

gcc version 2.95.3 20010315 (release)

GNU ld 2.11.2

All the above mentioned tools except gcc are built from source. I've also tried linking some of them with Sun's ld (/usr/ccs/bin/ld), resulting in the same link error (php uses libtool and GNU ld any way). If I leave out --with-openssl, building and linking goes fine.

My complete configure command:
# CFLAGS=-Os ./configure --enable-sysvsem --enable-sysvshm --enable-ftp \
--with-mysql=/usr/local/apachedeps --with-apxs=/usr/local/newapache/bin/apxs \
--with-zlib=/usr/local/apachedeps --with-bz2=/usr/local/apachedeps \
--with-jpeg-dir=/usr/local/apachedeps --with-tiff-dir=/usr/local/apachedeps \
--with-png-dir=/usr/local/apachedeps --enable-shared --enable-libgcc \
--with-freetype-dir=/usr/local/apachedeps --with-gd=/usr/local/apachedeps \
--with-gdbm=/usr/local/apachedeps --with-openssl=/usr/local/apachedeps \
--with-imap=/usr/local/apachedeps --with-config-file-path=/etc \
--with-gettext=/usr/local/apachedeps --with-db \
--with-prefix=/usr/local/apachedeps

This does not happen with php 4.0.5. It builds and links fine with (the same installation of..) OpenSSL 0.9.6a.
