Affects HEAD and FreeBSD 10.
	
>Description:

L_cuserid must match MAXLOGNAME.  When MAXLOGNAME was bumped to 33
in <sys/param.h>, L_cuserid in <stdio.h> was forgotten.

Fix: Bump L_cuserid to 33.

Alternatively, for HEAD, consider completely removing cuserid(3)
from libcompat and L_cuserid with it.
