This is possible when building Python on a Posix host, but not on Windows because of a missing PyAPI_DATA wrapping of the said object in the objimpl.h header. Having the possibility to inspect the PyGC_Head here can be very useful when customizing the way a garbage-collectable object created from CPython extension would be cleaned/inspected, etc. Any chance this patch could be added to get the same capabilities on Windows and Posix platforms ?
