[Python-Dev] Is "%zd" format is portable now?

Hi, snprintf() in VC 2010 had not supported "%zd" format. So we can not use it in PyOS_snprintf, PySys_WriteStdout, etc... But VC supports "%zd" format since (at least) VC 2015. See https://docs.microsoft.com/en-us/cpp/c-runtime-library/format-specification-... "%zd" is standard C99 feature. Can we assume it is portable for now? Regards, -- Inada Naoki
