[Rivet] rivet 2.4.2 with gcc 6.1

[David Grellscheid]

Hi Dimitri,

You're right about -ansi actually disabling the compiler default. Until 
we fix that in the next iteration, the flag you need in Rivet configure 
is --enable-stdcxx11. That should switch C++-11 mode on consistently, 
which will be sufficicent to make it work.

See you,

   David
