See: http://gcc.gnu.org/bugs.html#cxx_rvalbind which explains the problem. In a
nutshell:
-------------------------------------
struct A : boost::noncopyable {};
void foo(const A& a);

foo(A());   // ill-formed
-------------------------------------
but it used to be accepted, and it is still (wrongly) accepted by many
compilers.

Also I suggest you to have a look at http://gcc.gnu.org/gcc-3.4/changes.html to
see the main changes in GCC 3.4.0 that affects C++ code.
