That's why C99 introduced the "z" printf modifier, and approximately a billion ;-) format macros like PY_FORMAT_SIZE_T (since there's almost nothing portably useful you can say about standard C's billion names for "some kind of integer"). In effect, the PY_FORMAT_SIZE_T case was important enough that C99 moved it directly into the printf format syntax. > Would we have to detect when Py_ssize_t resolves to either int or long It's worse that that: there's no guarantee that sizeof(Py_ssize_t) <= sizeof(long), and it fact it's not on Win64. But Windows is already taken care of here. > OK, so how should we solve this one?

Note that if pyconfig.h defines PY_FORMAT_SIZE_T, pyport.h believes whatever that says. It's the purpose of "z" to format size_t-ish arguments, so gcc complaints should end then. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
