Hi Arjen,

thanks for your answer. I do know about these functions, and use them in my own programs if appropriate. However, programs
distributed to others for production use should not output this because it confuses users (as does "Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG" which I need to switch off with -ffpe-summary=none).

So I really am looking for strings or other type of info in the binary.

Best wishes,
Kay
