I downloaded the latest Sparse and don't see that warning.  But GCC has
a warning like that so I think this is really a GCC warning.  It doesn't
trigger for me, and with my config it's in fact, not a bug.  The buffer
is 19 characters and INIT_C_CC is 17 chars plus 1 NUL terminator.

All these things are generic termios defines so I'm not even sure how
you're triggering the warning.

Anyway, your patch is harmless enough.
