I'd encourage anyone that wants to see any of the technology for other 
reasons to migrate what they want into 3.5.  The srcloc_t (or whatever 
we call it) is an example of something that I think is good regardless 
of other issues.  I must admit that I don't see the use of it in your 
case.  Could you say a few words so that Per and I can ensure that it 
dove tails nicely.  I can't really push for it sooner, as I don't have 
a firm grasp of why it would be good to have now.  With the compile 
server it will be used to prevent the migration of information from one 
translation unit to another unrelated translation unit.  The canonical 
example for C++ would be:

bar.h:
void foo();

ba.h:
void foo() { ba(); }

bai.h:
void foo() { bai(); }

and the two units:

#include "b.h"
#include "ba.h"

and

#include "b.h"
#include "bai.h"

Now, personally, I'd like this to just be an error, but the language 
standard allows it.

Thanks.
