This is true, but nevertheless, POSIX does place strcasecmp in
strings.h.  It works on glibc and most other systems anyway, as there
is a second copy of strcasecmp in string.h, but that's not POSIX.
glibc systems actually define bcmp and index and the like in string.h
(unless strict POSIX is requested), so we aren't really avoiding those
functions by avoiding strings.h.

Unless the goal is to be locale dependent (for the group name stuff,
for example).
