OS - Windows7 x64
compiler - MSVC9
Boost version - 1.44

Running the following command fails to build the thread library with the 
following error:

bjam variant=release link=shared threading=multi runtime-link=shared 
--layout=tagged install

thread.obj : error LNK2019: unresolved external symbol 
"__declspec(dllimport) pu

_44.dll : fatal error LNK1120: 1 unresolved externals

Removing "--layout=tagged" from the command results in the thread 
library building successfully, but of course that isn't what I want :)
