IMPORTANT:
--enable-dio is NOT recognized as an option. After reporting a bug, i got following answer:
It is not bundled anymore. See http://pecl.php.net/dio to fetch the CVS version (being unmaintained, there is no release in pecl). Not a bug > bogus.

to use mandatory locking on a linux system, the filesystem has to be well prepared.
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hda1 / ext3 errors=remount-ro,mand 0 1
/dev/hda2 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
For example here the ext3 partition has been prepared for mandatory locking. Otherwise no dio_function will work on the system.

You can manually build the dio extension for your version of PHP, or install an older version of PHP that still bundled dio. It's not that hard to build it yourself, just a bit of a process, and it helps if you're on linux, and have a build environment... which I would assume you have if you are doing some kind of development that requires direct device I/O... Just get the dio source from the cvs repo, compile it, and then add the extension to your php configuration...
