Read the MSDN docs for AcceptEx().  It says you must include mswsock.h
and link to mswsock.dll to use this function, but you don't supply
-lmswsock on the link command.  It sounds like a bug in the Makefile.am
if these functions are used without adding the proper libs.  You can
probably work around it by adding it to LIBS, but it should be reported
as a bug to whoever maintains the Makefile.in/Makefile.am.

By the way, your current configure invocation uses the obsolete syntax
of providing overrides as environment variables.  The preferred method
is to supply them as command line arguments:

./configure --prefix=`cd /opt && pwd -W` \
  LDFLAGS="-L/boost/lib" \
  CPPFLAGS="-I/boost/include/boost-1_33_1" \
  LIBS="-lmswsock" && make

The only time you should use the other form is when dealing with an
older autoconf 2.13 package.  Also, for most MinGW packages you need to
use a win32 path for prefix, so --prefix=`cd /opt && pwd -W` is what you
should use.

Same here.
