I remember that we discussed this problem before:

C:\Projects\boost-git\boost>b2 --with-system toolset=msvc-10.0 
address-model=32,64

[...]

error: Name clash for '<pstage\lib>libboost_system-vc100-mt-gd-1_61.lib'
error:
error: Tried to build the target twice, with property sets having
error: these incompatible properties:
error:
error:     -  <address-model>32
error:     -  <address-model>64
error:
error: Please make sure to have consistent requirements for these
error: properties everywhere in your project, especially for install
error: targets.

but don't remember what we concluded. Will we support building both 32 and 
64 bit libraries under Windows? At present if I want to have an IDE project 
that has both Win32 and x64 configurations I need to build the 32 bit 
libraries, move them out of stage/lib somewhere, then build the 64 bit 
libraries, then move them out of stage/lib to somewhere else, and set my 
library directories in the IDE accordingly.

It would be much more convenient if 32/64 were encoded into the name, so 
that I can leave my library path to point at stage/lib and rely on autolink 
to choose the right .lib file automatically, like it works today for the 
other options (debug/release, static/dynamic runtime).
