I have looked a bit more at this. That #define was put in by Andrew in
revision 12340 in May this year as part of his large numeric removal
and accompanying numpy fixup change.  So it is not that old a change.
>From his commit message it helped insure the code was clean (no
compiler warnings) when compiled with numpy version 1.7, but, of
course, that would only be a check of the part of our Python/numpy
interface that is used in the Linux case, and from your experiences
there appear to be other bits left for the Windows case that are not
yet clean for numpy 1.7.  For my previous tests of Python/numpy on my
Debian wheezy platform, numpy is version 1.6.1, and for the
MinGW/MSYS/Wine platform I chose to use numpy-1.5 so I have
effectively bypassed all numpy API checks on both Linux and
MinGW/MSYS/Wine. But when I move to numpy-1.7 for my python/numpy
tests on MinGW/MSYS wine (hopefully later today) I anticipate I will
run into the same warnings you encountered about code not being
numpy-1.7 clean.  With luck I should be able to fix all of those and
as a result we should be clean against numpy-1.7 API in the Windows case.
