I can't do a build on current with a recent sup ( MArch 10 ):
Here's a sample ( I disabled -Werrors ):

cc -O -DDEBUGSHELL -DSECURE   -c init.c
In file included from init.c:67:
/usr/include/unistd.h:54: warning: `noreturn' attribute directive ignored
init.c: In function `handle':
init.c:299: too many arguments to function `__builtin_next_arg'
init.c: In function `delset':
init.c:333: too many arguments to function `__builtin_next_arg'
init.c: In function `stall':


I get the same 'noreturn" warning from /usr/include/err.h in lines 56-59 .
