I suspect that it might be something relevant to Windows ports.  I can't see a 
problem with the change you suggest, but I'd like to understand what this was 
for in the first place as I'm cautious when it comes to things that require 
changes to the ports - we need to have a good reason for them.  Is there 
anything stopping you defining ERRNO in your port or compiler, as I think that 
will yield the code you need.
