Right, GDB's baseline is GCC 4.8 too. When GDB was deciding whether
to start requiring full C++11 (about a year ago), we looked at the
latest stable release of all the "big" distros to see whether:
#1 - the system compiler was new enough (gcc >= 4.8), or failing
that,
#2 - whether there's an easy to install package providing a
new-enough compiler.
and it turns out that that was true for all. Meanwhile another year
has passed and there have been no complaints.
