Compile issue with different ARM Cortex-M0+ boards #4
Description
The example code compiles correctly on my computer using Arduino IDE 1.8.13 and the Teensy LC board. The Teensy LC uses an ARM Cortex-M0+ processor. The board I am trying to use for my project is also an ARM Cortex-M0+ made by Seeeduino, the XIAO.
The Teensy LC compiles without any errors using your example program.
Changing the board to the XIAO gives several pages of errors.
Below are just the first few that have files for both the seeeduino board and eigen library listed:

I am assuming these errors are related to the C libraries that the Seeeduino board uses in the arduino compiler, from the ..\Seeeduino\hardware\samd\1.8.3\cores\ folder.
Some of the errors show headers from the eigen library as well that I assume are because of the errors with the Seeeduino code.
Do you know if there is any work around for these? My skill set is pretty limited in dealing with compilers and any core files for the boards.
Thank you
