Description
Describe the bug
I am sure we have all seen this, but figured there should probably be an issue for it:
I have run into a lot of existing sketches including examples that do not build properly on zephyr
as it will give you errors saying that some function is not defined in the current scope.
Target board + cli verbose compilation output
In this case I am building for the GIGA
Full verbose compilation output, ideally witharduino-cli invocation or from IDE 2.3.3+

I last run into it trying to build the PDM example to see if I can get the PDM library to build and run on
Zephyr... but that is something to discuss on it's own
