Comment (by jhpalmieri):
On two OS X systems (one 10.9, one 10.10) this builds successfully but
takes longer to build than previous gcc's. Is that the nature of version
4.9, or are we building extra stuff?
The time difference: on an old slow machine, it took 58 minutes to build
4.7.3 and 101 minutes to build this. On a newer faster machine, it took 16
minutes to build 4.7.3 and 21 minutes to build this. This time increase
was also true with version 4.9.1. Do you see this on other platforms?
