We've required gcc-6 for ARM since v2018.01, and we were warning about that for a while longer than that, due to toolchain issues. That said, my commit message is clearly not clear enough. We don't require gcc-6 for everyone, we require support for -std=gnu11, and that goes back a long ways. It's just that since some platforms require gcc-6 we've started having (and this is good, the code is cleaner!) some C-11'isms sneak into the code. For example, sandbox now fails to compile on older hosts due to a for (int i = 0; ...) in cmd/iotrace.c -- Tom
