No, the stdlib.h stuff is only warnings, the error is that it tries to
use a struct hayes_esp_config because the kernel headers on x86 has the
TIOCGHAYESESP ioctl defined in asm/ioctls.h (E.G. on ARM it isn't
defined, and there it builds).

The hayes stuff is for a really ancient driver (which has recently been
removed by Alan Cox).

As far as I can see, this has nothing to do with uClibc - Did you
recently change the kernel headers version?

As for a fix - We could add an #undef TIOCGHAYESESP after include
<linux/serial.h>, but I would like to know when the problem started first.
