Comment 1 for bug 1836698

When adding build_flag = -E, the setup function in generated main.cpp.o file looks like this

void setup() {
  SerialUSB.begin(9600);
  while (!SerialUSB);

  char buffer[512];
  uint8_t value = 123;
  snprintf(buffer, sizeof(buffer), "value=%"
# 18 "src\\main.cpp" 3 4
                                            "hh"
# 18 "src\\main.cpp"
                                            "u" "\n", value);

  SerialUSB.print(buffer);

  SerialUSB.print("PRIu8=");
  SerialUSB.print(
# 23 "src\\main.cpp" 3 4
              "hh"
# 23 "src\\main.cpp"
              "u");
}
