Maybe we could poke this? https://bugs.python.org/issue11717 Apparently ssize_t is not defined on Windows (it's from POSIX, not C) and various projects step on each other's toes defining it. On 64 bit systems we both use __int64. On 32 bit systems, we chose long and they chose int. If we changed our definition to use int too, I assume that would fix the warnings here but might risk creating the opposite problem somewhere else... -- Thomas Munro http://www.enterprisedb.com
