I executed (long lines wrapped)

boost_1_33_1$ bjam -sTOOLS="mingw"
-sMINGW_ROOT_DIRECTORY="/usr/i586-mingw32msvc"
-sGCC="i586-mingw32msvc-gcc" -sGXX="i586-mingw32msvc-g++"

and I got:

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).

Why bjam is trying to create .so instead of .dll's? And what about the
problem with -fPIC?
