/*
 * Xtensa toolchain declares `int32_t` as `int` but RISC-V toolchain
 * declares `int32_t` as `long int` which causes compilation errors.
 *
 * See:
 *   https://github.com/espressif/esp-idf/issues/6906
 *   https://github.com/espressif/arduino-esp32/issues/5086
 *
 * You need to add the following lines in `build_flags`:
 *                            -I$PROJECT_DIR/include
 *                            -include "esp32x_fixes.h"
