No, it is more than two months younger.  But it was built on a different
machine (and different OS).  As I explained a few times already, I put
it there to help people who cannot easily build a compiler with Ada
support (because centos does not ship that currently).

And it in fact works fine for that.  I used it yesterday to build that
gcc8-r257824, which will work for more things (it has a working libstdc++,
or at least the GCC testsuite didn't complain).

GCC 7 RC2 is essentially identical to 7.0.1 fwiw.
