You forgot one solution: 5) Win32 for WindowsCE doesn't have errno, just like it doesn't have any getcwd() and co. If the user is porting code with mingw32ce which uses this, either use it's own replacements or use cegcc. I'm with 5. For me, mingw32ce is the thin wrapper around the WinCE Win32 API, so don't try to add functionality that doesn't exist already on the standard SDK. The possible exception may be the implementation of the minimum required to build a minimal C++ standard library, but I would not worry about iostreams and such (anyone using iostreams on WinCE, instead of using the lower level API is probably going in the wrong direction anyway). Also, many things weren't available on earlier WinCE versions that are now on recent versions, so there's the risk of implementing too much and make the programs not compatible for the future. And, most of the missing "standard" C runtime functions are implemented in the MFC libraries, so a latter support for MFC applications compiled with mingw32ce could become messy if we do too much now. I don't mind having a separate helper library for mingw32ce but, for me, anyone using errno with mingw32ce will always get into trouble latter (there's no way to correctly map the errno errors with the GetLastError() results).
