Not really. This is the idea - msvc initialization will remain intact
while psdk.jam will register additional INCLUDE, LIB and PATH that will
overload with the settings set by msvc.

amd64/ia64 compiler from PSDK is enabled by adding some PSDK directories
to PATH. So if the action is something like this:

actions ...
cl.exe ....

$(SETUP) can be a list of commands 'set PATH=...;%PATH%'. These commands
will setup the environment we need.

I don't know yet. I suppose we can set addition flags for
compiler/linker/assembler tool. Their value will depend on selected
<architecture> etc. settings.

Sounds like you want to post a patch implementing this. :-)

Sorry, I meant that passing a condition to the init rule can be
implemented but I don't think it is the best way to solve the problem
with amd64/ia64 compilers from PSDK.
