David Cooke informed me some time ago that the #include
"numpy/arrayobject.h" line should go _after_ the other #includes. It's
worked for me well enough ever since, although it seems rather fragile.
Otherwise I'm not having the same issue with current svn. There was an
issue with release 0.9.4 for C++ code, anyway.
