In configure of Pytave the numpy test is passed (Thanks to Abhinav!)

Current configure command 

export PATH=$PATH:/c/msys64_gcc530/usr/bin:/c/Python27:/c/Python27/scripts
export CPPFLAGS='-I/c/Python27/include 
-I/d/usr/Tatsu/program/Pytave/PytaveBuild/boost/boost_1_16_inst/include'

export LDFLAGS='-L/c/Python27/libs 
-L/d/usr/Tatsu/program/Pytave/PytaveBuild/boost/boost_1_16_inst/lib'
../pytave/configure LIBS="-L/c/Python27/libs" 
--prefix=/d/usr/Tatsu/program/Pytave/PytaveInst

The origin of failure is 

D:\usr\Tatsu\program\Pytave\PytaveBuild\Pytave\build/conftest.cpp:17: undefined 
reference to `__imp__ZN5boost6python6detail11init_moduleEPKcPFvvE'

This kind of undefined reference error sometimes happens on windows build. 

I do not have a good solution at the moment.
(Sometimes dynamic link library will solve the problem but I failed to build 
the dynamic link libraries boost_python. 
I do not know the reason)
