Multiply defined symbols with --enable-sockets

I'm trying to build PHP 5.2.9 (26 February 2009 release).

The build fails with multiply defined globals when I enable the sockets
extension.

I'm using this configure line:
cscript /nologo configure.js  "--enable-debug" "--enable-apache2-2handler"
"--with-gd" "--without-t1lib" "--enable-soap" "--enable-pdo"
"--with-mysql=libmysql" "--with-mysqli" "--with-pdo-mysql" "--with-openssl"
"--enable-sockets"

This is the result:
flock_compat.obj : error LNK2005: _inet_aton already defined in
php_sockets_win.obj
flock_compat.obj : warning LNK4006: _inet_aton already defined in
php_sockets_win.obj; second definition ignored
   Creating library Debug_TS\php5ts_debug.lib and object
Debug_TS\php5ts_debug.exp
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs;
use /NODEFAULTLIB:library
LINK : warning LNK4049: locally defined symbol "_php_dom_create_object"

defined symbols found
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual
Studio\VC98\BIN\cl.exe"' : return code '0x2'
Stop.

It is my understanding that the LNK4098 and LNK4049 are usual and just
noise.

I was having this problem last week with PHP 5.2.8 and it was recommended
that I get the latest CVS. Since 5.2.9 has been released, I decided to just
move up to it.

This is something of a show-stopper at the moment.
Assistance clearing it up  would be appreciated.

Thanks in advance,
Dave
