I found something. If platform.h is included as etl/platform.h compile will be successful.

Successful:

// test1.cpp
// g++ test1.cpp -o test1 -DETL_NO_STL -Iinclude

#include "etl/platform.h"
int main() {
    return 0;
}

Compile error:

// test2.cpp
// g++ test2.cpp -o test2 -DETL_NO_STL -Iinclude/etl

#include "platform.h"
int main() {
    return 0;
}
