I just upgraded an old (unused, underpowered) box to 16.10 as a first
test. No issues so far, and basic cppFunction("...") tests with Rcpp work.
Could you get us a minimal reproducible example of what broke without the
explicit -std=c++98 ?
When I posted, there was only "xenial", not "yakkety", on CRAN. This has
changed now (thanks a lot!). When I try to upgrade, I'm presented with
the following diff of /etc/R/Makeconf (excerpt), which looks *very*
strange to me.

Also, no "-std=c++98" in the maintainer's version.
I noticed this because plogr logging crashed in dplyr (compiled with gcc
6) right after upgrading to yakkety; I still had a gcc-5 built version
of Rcpp installed. As soon as I added -std, everything worked as before.
No minimal example, sorry. Don't we need "-std=c++98" in Makevars
anyway, even if it's just to avoid users using C++11 constructs and then
wondering why their packages fail on CRAN?
