I just updated my current sources and did a buildworld and buildkernel.

This warning was spit out, although it didn't result in buildkernel
failing:

In file included from /usr/src/sys/teken/teken.c:70:
/usr/src/sys/teken/teken_wcwidth.h:128:1: warning: unused function
'teken_utf8_bytes_to_codepoint' [-Wunused-function]
teken_utf8_bytes_to_codepoint(uint8_t bytes[4], int nbytes)
^
1 warning generated.

Just FYI.
