I tried switching userland to -std=c11. I ran into several issues:
/home/riastradh/netbsd/current/src/lib/libc/ssp/stpncpy_chk.c:46:1: error: no
previous prototype for '__stpncpy_chk' [-Werror=missing-prototypes]
46 | __stpncpy_chk(char * __restrict dst, const char * __restrict src,
size_t len,

/home/riastradh/netbsd/current/obj.riscv/tooldir/bin/../lib/gcc/riscv64--netbsd/12.4.0/../../../../riscv64--netbsd/bin/ld:
libamu_pic.a(ualarm.pico): in function `__sigaddset14':
/home/riastradh/netbsd/current/obj.riscv/destdir.riscv/usr/include/signal.h:118:
multiple definition of `__sigaddset14';
libamu_pic.a(xdr_func.pico):/home/riastradh/netbsd/current/obj.riscv/destdir.riscv/usr/include/signal.h:118:
first defined here
I made progress after the first one by adding
char *__stpncpy_chk(char *, const char *, size_t, size_t);
to include/ssp/string.h but I'm baffled how this could possibly work
because the definition in lib/libc/ssp/stpncpy_chk.c has __restrict
qualifiers, which should surely be rejected given this prototype, no?
Getting userland to build with -std=c11 instead of -std=gnu11 might be
a bit more trouble than I want to deal with right now.
