It is not the problem what the people do. It is a very big problem for distributors. All Distributors have a glibc on Alpha without __register_frame_info. Nobody could do the switch and use a new compiler. The first who do this becomes big problems with software vendors, because they couldn't use this distribution as development platform for all Linux distributions. Yesterday I got an email, if it is really necessary to make three versions of his product: libc5, glibc2.0 and glibc2.1. Should he now make 4 ? one with register_frame_info, one without ?

It is incredibly powerful, gives terse, cryptic answers and has a lot of things going on in the background.
