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).
