If available version number as major, minor, and patch.
The patch number is derived from `_MSVC_STL_UPDATE` by taking its five last
digits (see below). This implies that pasting a `_MSVC_STL_UPDATE` value into
`BOOST_VERSION_NUMBER` will produce a version number that is directly comparable
to `BOOST_LIB_STD_MSVC`.
