Fail building wrapp.cpp.o

[AlexisLeC]

Dear all
I tried to build Boost.NumPy with python3.4, np 1.8.1 and boost 1.55.0 on ubuntu

First build with CMake-init.sh went right but when i tried to "make" in the created build directory I came up againt an error when building the wrap.cpp.o in the example directory?

[ 68%] Building CXX object libs/numpy/example/CMakeFiles/wrap.dir/wrap.cpp.o

In boost/python/module_init.hpp, the name of this initation function is generated as init + example (module name) for Python2 and PyInit_ + example (module name) for Python3.
When I replace initexample with PyInit_example, it works.
This function name is generated as a part of function definition,
and there is no macro to generate function name only.
Only way to avoid this is to switch the function name using preprocessor:

# if PY_VERSION_HEX >= 0x03000000
    PyImport_AppendInittab("example", &PyInit_example);
# else
    PyImport_AppendInittab("example", &initexample);
# endif

Fixed in #39.
