Hi,
I'm trying to get p4python (perforce python API) compiling with pypy
and I notice that the include headers in pypy are very different than
the standard 3.2.5 python headers. Is the C api different for pypy3
from python 3.2.5?
For example, note the following diffs:
---------------------------------------------------------------------------------------------------
diff -c `find . -name moduleobject.h`
*** ./pypy3-2.3.1-linux-armhf-raspbian/include/moduleobject.h
2014-06-19 09:20:58.000000000 -0700
--- ./Python-3.2.5/Include/moduleobject.h 2013-05-15
09:33:41.000000000 -0700

When I compile against the distributed pypy3 headers, I get errors:

If I hack around the macro problems, I can get a compile, but then I
get a runtime error:

Any help appreciated..
