Our <termio.h> currently is just:

#include <termios.h>
#include <sys/ioctl.h>

Maybe you could send a header diff of what you want to remove?  We have
some heuristics to determine the source-level impact.

Are there ioctls that need to kept, but that would be incompatible with
the new B… constants?

Thanks,
