Hi all,

Invoking 'bjam --v2' in boost/libs/filesystem/build results in following 
error message:

C:/cvstop/boost/tools/build/v2/util\path.jam:336: in make-NT
*** argument error
* rule path.join ( elements + )
* called with: ( )
* missing argument elements

I can't figure out why this is happening. I'm new to version2 though 
since we are trying to migrate from version1 to version2. The problem 
seems to be that the variables $(os) and $(native) passed on to 
path.join are both empty.

On a related note I wonder when the variable 'os' is initialised. It is 
declared in global scope in path.jam and not somewhere in a function.
