- There is an ambiguity here in 1003.1, and the interpretations committee
- is working on it. It is also being worked on in 1003.1a, and the current
- state of that draft document is that the namespaces are separate like
- ANSI C.
-
- I won't presume to predict the interpretations commitee's resolution.
