New submission from Stefan Behnel:
Formatting support for "lld"/"llu" was added (I think) in issue 7228, but the definition of PY_FORMAT_SIZE_T wasn't adapted. We are getting test output failures in Cython on Win64 when formatting error messages using the "Id" format, as defined by pyport.h:
"""
#ifndef PY_FORMAT_SIZE_T
# if SIZEOF_SIZE_T == SIZEOF_INT && !defined(__APPLE__)
# define PY_FORMAT_SIZE_T ""
# elif SIZEOF_SIZE_T == SIZEOF_LONG
# define PY_FORMAT_SIZE_T "l"
# elif defined(MS_WINDOWS)
# define PY_FORMAT_SIZE_T "I"
# else
# error "This platform's pyconfig.h needs to define PY_FORMAT_SIZE_T"
# endif
#endif
"""
The "%Id" format is not being resolved in the error messages and shows up in the output instead.
NumPy uses "lld" when available, starting with Py2.7:

Shouldn't PY_FORMAT_SIZE_T become "ll" on Win64 directly?
