#include <Servo.h> compile error for Metro M4 Express

#include <Servo.h> results in a compile error for the Metro M4 Express

#include <Servo.h> int main(void) {}

What I've Tried I have tried using the standard PlatformIO <Servo.h>. See logs below. I have tried rebuilding the library from Adafruit's version. See logs below. This same header compiles fine on the Arduino IDE with this BSP. Per this issue, the latest BSP has a working Servo library. See logs below.

Expected Outcome #include <Servo.h> compiles without error. PlatformIO matches the Arduino IDE in header support for Metro M4.

Using Adafruit's Library

Per this forum, I download this .zip , renamed it to 'Servo', then copied it to my PlatformIO project's 'lib' folder.
