Exactly.

Honestly, I have no idea.

Basically 'msplatformsdk.jam' I posted recently is more or less 
'tools/windowssdk.jam' you are talking about.

The main difference is that 'stlport' injects 'stdlib' library target 
into the dependency graph while 'msplatformsdk' has to modify INCLUDE, 
LIB and PATH. INCLUDE and LIB have corresponding BBv2 abstractions 
(still there are some issues with order of directories) but the only way 
to change PATH - issue corresponding command from each action. That is 
why 'msplatformsdk'-aware toolset should explicitly do MS PSDK 
initialization in each action.

BTW during development I considered another possibility: if BBv2 had 
some kind of 'environment initialization' functionality I would use it. 
I mean that 'vcvars32.bat' for example could be called only once before 
executing all other actions. This requires support in 'bjam.exe' as far 
as I understand.

Oops! :-) Thanks.
