mingw executable is: i586-mingw32msvc-g++
If you follow the links to the description of the gcc (or mingw) toolset you'll see that the environment variable GXX can be set to the name of the executable to use, you'll need to set that in addition to the usual mingw setup options described in http://www.boost.org/tools/build/v1/mingw-tools.html
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.

And what about the problem with -fPIC?
