Re: [Python-Dev] Symbolic errno values in error messages

Until recently, python had its own cross-platform implementation of strerror, but it was removed because it was deemed redundant. This tells me that it should work on windows.

That conclusion is incorrect. It works on MSVCRT, but for this specific aspect, using MSVCRT is a bad idea (because it artificially renumbers system errors, just to provide an illusion for what Microsoft considers POSIX). Regards, Martin
