I agree that it is time to re-visit these issues and they are going to apply to more than just the Filesystem library. I don't believe The E* names are portable to non-posix systems which includes ( at least part of ) Windows.
Strictly speaking, E* isn't directly portable to anything. Every system provides a mapping from its native error codes to E*. This is exactly what the filesystem library does at the moment, except that it maps to its own set. (The GetLastError to E* mapping that the MSVC runtime does is in crt/src/dosmap.c, but it looks like it can be improved.) I don't see a reason for us to reinvent the wheel yet again when the work of coming up with a portable set of error codes is already done (by a standard committee, no less).
