Bug in GCC 4.5 c++0x version of std::list<T>::merge(&&)?

[Benjamin Redelings I]

Hi,

     Some of my code compiles without -std=c++0x, but not with it.  It 
seems to be the result of the following snippet:

         list<_Tp, _Alloc>::
#ifdef __GXX_EXPERIMENTAL_CXX0X__
     merge(list&& __x)
#else
     merge(list& __x)
#endif

For c++0x, don't we need both versions, now that the standard has been 
modified so that rvalue references cannot bind to lvalue references?
