Expected Results

Sketch compiles successfully.

If problems with PlatformIO Build System:

The content of platformio.ini:

platform = teensy
framework = arduino
board = teensy30

Source file to reproduce issue:

#include <math.h>

typedef struct Location {
  char name[16];
  double lat;
  double lng;
} Location;

double distance(Location from, Location to) {
  return sqrt(pow(from.lat - to.lat, 2) + pow(from.lng - to.lng, 2));
}

I've rewritten INO to CPP converter in 2.9.0. Please try the latest development version. Does it work?
