Re: [boost] BOOST_NO_EXTERN_TEMPLATE check is broken

The current Boost.Config check for BOOST_NO_EXTERN_TEMPLATE uses incorrect syntax.

Grepping through the compiler configurations, BOOST_NO_EXTERN_TEMPLATE is set for several compilers that do in fact have support for C++0x extern templates, namely GCC and EDG-based compilers (when in either in C++0x or non-strict mode).

Tentatively fixed in Trunk, thanks, John.
