Compiling boost 1.33.1

Today I decided to update the boost library on my machine. And I got a strange error in attempt to compile Boost.Jam (bjam):

G:\boost_1_33_1\tools\build\jam_src>build
\Utilities\Bin\x86 was unexpected at this time.

The problem was solved after (temporary) removing the following path
from PATH environment variable:

H:\Program Files\Microsoft DirectX 9.0 SDK (October 2005)\Utilities\Bin\x86;

Seems like build.bat (or callee of it) do not like scopes in the PATH.
