Compile error with 4M1M with latest source from today

[Micha_he]

I've update today to the latest source/patches and start compuile a 'normal_ESP8266_4M1M' firmware.
While the build-process the following errror is displayed:

Is the problem at my vscode/platformio environment ? Can I solve the problem ?

That's not an error, but a warning.

Ok, when I can ignore it..... The bin-file is created and seems to work.

Yep this one you can ignore.
I will have a look at the warnings later.
Some other libraries also have warnings and even our own code has warnings which aren't so innocent as this one.
