As far as I can see, you still haven't explained what the "problem" 
actually is. Does it fail to compile or link? What's the diagnostic 
message, then? Could you, please, elaborate?

Ah, I understood the question as being skeptical about the diverging 
implementations. And in this respect, it is *not* wrong. Looking at it 
from the standard compliance perspective, though, I agree it's illegal.

The thing is, that CLN will not be modified unless somebody
a) writes a patch and/or
b) explains how to find the bugs in a systematical way.

See, it happens to work just fine on all machines I tried and I'm not at 
all inclined to read source code and check it for standard compliance 
line-by-line.

Please, explain what's the matter, or, better, send us a patch.

Best wishes
