enable dmalloc option for php 4.1.1

We tried to install php 4.1.1 on our Solaris 2.8 machine with gcc 2.95.2 and apache 1.3.22. We tried to enable as many configuration options as possible. It configured OK, but we encountered several error messages during compilation: We configured with option "--enable-dmalloc" and "--with-apxs", the error messages we got are: In file included from /depot/package/apache_1.3.22/vendor/include/ap_config.h:1160, from /depot/package/apache_1.3.22/vendor/include/httpd.h:72, from mod_php4.c:32: /usr/include/memory.h:20: conflicting types for `_dmalloc_memccpy' /depot/include/dmalloc.h:435: previous declaration of `_dmalloc_memccpy' /usr/include/memory.h:35: conflicting types for `_dmalloc_memchr' /depot/include/dmalloc.h:437: previous declaration of `_dmalloc_memchr' /usr/include/memory.h:37: conflicting types for `_dmalloc_memcpy' /depot/include/dmalloc.h:424: previous declaration of `_dmalloc_memcpy' /usr/include/memory.h:38: conflicting types for `_dmalloc_memset' /depot/include/dmalloc.h:426: previous declaration of `_dmalloc_memset' *** Error code 1 make: Fatal error: Command failed for target `mod_php4.lo' Current working directory /site4/web_kit_1.0_rodgers/php_4.1.1/sapi/apache *** Error code 1 make: Fatal error: Command failed for target `all-recursive' When we built apache, there is no options for "dmalloc", does that mean we could not enable dmalloc in php too?
