No.  I mean that in order for Boost.Build to
know that 3.4.5 is the version (and not some
other subfeature), either there has to be a

using gcc : 3.4.5 ;

or the version deduced by running gcc --version has
to be 3.4.5.  The point is that target alternatives
whose requirements include unknown subfeature values
have to be ignored.
