- <strings.h> is a portable SUS/POSIX header:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/strings.h.html
- "popcountl()" in NetBSD's <strings.h> is either a
standards-nonconformance issue, or the the qemu build system doesn't set
up the right SUS/POSIX environment for compilation on NetBSD. (If that's
possible at all, I don't know.)
