I can get 4.0.3 to compile if I edit php_config.h and swap the following:

/* whether you have POSIX readdir_r */
/* #undef HAVE_POSIX_READDIR_R */

/* whether you have old-style readdir_r */
#define HAVE_OLD_READDIR_R 1

with
/* whether you have POSIX readdir_r */
#define HAVE_POSIX_READDIR_R 1

/* whether you have old-style readdir_r */
/* #undef HAVE_OLD_READDIR_R */



However, I then get "bus error" when I try to use 4.0.3...

The configuration I used was:
./configure \
--with-gd=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local \
--with-xpm-dir=/usr/local --with-mysql --with-zlib \
--enable-track-vars --with-apxs=/usr/local/apache/bin/apxs \
--enable-versioning --enable-force-cgi-redirect --enable-yp
