Forgot to say: I believe those were ANSI-dictated math functions in libc (as opposed to non-ANSI-dictated math functions relegated to libm.so.1 for obscure Unix-historical reasons). So, that was a rare case of selective software sensitivity to a CPU problem -- but even then its expression was limited to libc.
