Fwiw, GCC 4.10 was renamed to GCC 5 before it was released (it was the first release with the new version number scheme). Only old development versions (that no one should use) identify as 4.10.

Yes, esp. since some versions of 4.9 and 4.8 are still buggy. No one should use any version for which a newer bug-fix release has long been available, but do you want to deal with bugs from people who do not?
