I think I'd object to having it turned on by default.  I certainly would 
not argue in favor of it being compiled in but not turned on.

In my last message, I meant to point out that once you have lots of 
messages which are the same, in the name of making things clear, being able 
to build a version with line numbers is useful for finding the right code 
path.

I do not think line numbers are terribly useful in end-user/OS builds, 
since by the time you get a problem report you will often either not know 
what source was used or not have a copy.
