Well, if I were running the show, the 'clock' would only start
running
when it was consensus among the libstdc++ developers that the soname
would not be bumped again - that henceforth libstdc++ was
committed to
binary compatibility as good as glibc's. Or better, if y'all can
manage
it. It doesn't sound like we're there yet, to me.
Why can't libstdc++ use symbol versioning? glibc has maintained
the soname
and binary comptiblity despite changing fundamental types like FILE
Please stop spreading rumors:
1. libgcc changes with compiler release. glibc is loving libgcc. ergo:
glibc has not maintained the soname and binary compatibility.
2. The whole linker tricks glibc plays to accomplish this
are not portable and not applicable to C++ code.
3. Threads are the death to glibc backward compatibility.
