New Revision: 69402
URL: http://svn.boost.org/trac/boost/changeset/69402

Log:
Added predator_prey.cpp target.  It's just an
example file; however, it does illustrate
an actual problem posted to comp.lang.c++.
Unfortunately, it's only been successfully
tested using bjam builder and with:

  ftp://gcc.gnu.org/pub/gcc/snapshots/4.6-20110129/gcc-4.6-20110129.tar.bz2

In constrast, with:

  ftp://ftp.gnu.org/gnu/gcc/gcc-4.5.1/gcc-4.5.1.tar.bz2

the following error message is produced:

predator_prey.cpp:227:53:   instantiated from here
../../../../boost/composite_storage/pack/multiple_dispatch/reify_apply.hpp:131:41: error: conversion from 'void' to non-scalar type 'boost::composite_storage::pack::multiple_dispatch::ptrs_target0_source<>::type' requested

Curiously, using gmake and the 4.5.1 compiler, the this error does not occur.
