Hi Steve,

Could I get some more information on this problem before we hack the
library or you add a fixinclude? ;-)

The line of code in question has been present since Jan 02.  How long
have you seen this problem on mainline?

Does the standard say that ``using ::abs'' will not pull an inline
into the new namespace scope exactly as it would an extern?  I'm
surprised to hear that.  I.e. the following compiles for me with
mainline:

inline void a(void) {}

namespace std { using ::a; }

Thus, I'm wondering what is different in your case.  Could you post
for us the exact declaration found in your system's <stdlib.h> in C++
mode?

Regards,
Loren
