That's what I thought. So, I found it strange that I'm still getting those messages with the 1.60 b6 PlatformIO build. Maybe I'm doing something wrong. I can probably manually add the flag to get rid of those messages but I wonder why that is not automatically happening?It's mostly a pointless warning for Arduino-like projects though since they typically don't use prebuilt libraries. I posted about this a while ago and Paul changed the necessary build flags to get rid of it in the first 1.6.x beta.
