Hello,
I am using cygwin on a Windows XP system. I can build boost 1_32.0 with
no problems. If i Try to build boos_1.33 The build failed with the
following error:

./bjam -sTools="gcc" --prefix=/usr stage
Building Boost.Regex with the optional Unicode/ICU support disabled.
Please refer to the Boost.Regex documentation for more information
(and if you don't know what ICU is then you probably don't need it).
unknown target type for
<@boost!libs!test!build>libboost_prg_exec_monitor.dll

The error doesn't depend on prefix. 

what is wrong ???

buy
