Component:  None                      |     Version:  Boost 1.50.0

--------------------------------------+-------------------------------------
 When building with `toolset=msvc address-model=64` in a 32-bit shell on
 Win64, the cross tools (32-bit targeting 64-bit) instead of the native
 64-bit tools are used. The reason is the `PROCESSOR_ARCHITECTURE` env var
 pretending to be a 32-bit environment. However, on 64-bit Windows, the
 correct native value can be found in `PROCESSOR_ARCHITEW6432`.
 The attached patch makes the logic to determine the tools to use respect
 that alternative variable.
