[Boost-build] Runtime 'g' tag

I believe http://boost.org/more/getting_started.html may be conflating
the compiler's runtime support library with the standard library
(which admittedly are sometimes the same).  Consider the case
mentioned there:

  For example if you compile debug code for STLport using native IO
  streams, and statically link to the debug runtime the tag would be:
  "-sgdpn".

STLPort's native IOstreams feature means there's no compiled STLPort
binary. I presume that when not using native iostreams, 'g' selects the
debug version of the STLPort binary.  When using native iostreams,

  * Does it enable STLPort debug mode?
  * Does it use a debug version of the compiler's runtime library?

TIA,
