This is just a wild guess, but what happens when you reorder your compile 
command, putting the libraries _after_ the source file, like this:

g++.exe -O0 - shared \
   -Ic:\development_compiler\_boost\include\boost-1_34_1 \
   -Ic:\development_compiler\python25\include \
   -Ic:\development_compiler\mingw\include \
   D:\Temp\boost_test\hello.cpp \
   -Lc:\development_compiler\_boost\lib \
   -Lc:\development_compiler\python25\libs \
   -Lc:\development_compiler\mingw\lib \
   -lboost_python-mgw34-mt-s-1_34_1 -lpython25 \
   -o hello.pyd

[...]
