It is not too difficult, it is time consuming. And we do not have much  
free time now. Therefore I am looking for some temporary solutions to  
make our code better. Now I see that my proposal is not very realistic  
to implement from your point of view.

I know that you have to stick with your release plans, so this is not  
something to expect soon. I understand this. What I am looking for are  
things which I could use now; I thought there may be something in gcc  
already to help me with my work now, so I asked here.

I also look for long term solutions which could be helpful for me and  
for others, so I asked more questions. Sorry if I annoyed you.

Thank you for your answer. I will wait for some more feedback on my  
last proposal about adding and using this extra info, and log and  
enhancement.
