 At this point, I switched to using the bash shell present with octave.

+(cflags, cxxflags, and linkflags are needed when python27 are not installed not to default directory. (default C:/Python27 )
+At this moment building of boost-python with 64 bit tool chain fails at final link stage. Using 32 bit octave 4.1.0+ for windows build of boost_python was successful.
+So far octave-4.1.0+ 32 bit has been used.

+# Open octave-cli.exe

+# system bash
+# export PATH=$PATH:/c/msys64/usr/bin
+# ./configure (with CPPFLAGS LDFLAGS setting )
+# make
 There was an error in configure that PYTHON_EXTRA_LIBS was 'None' on windows and hence the configure failed. As per Mike's suggestion I set it to a valid gcc flag for the time being with ''export $PYTHON_EXTRA_LIBS=-g''
 After this too the build failed with undefined references to few symbols. Tatsuro suggested to build boost with ''link=static,shared''. He had successfully built boost with it but I could not build boost with this option on my PC.
