I'd much prefer a separate module 'xstrndup', because
  1. Not everyone who needs xmalloc needs xstrndup (in particular
     gettext doesn't need it),
  2. xalloc is a general purpose memory allocation facility, whereas
     xstrndup is a string processing facility (extracting a substring
     of a string, starting at 0).

Instead of rolling an implementation with a FIXME, why don't you take
the implementation from Bison?

Also, a xstrndup.h file is missing. We no longer want functions that
are not declared in .h files! lib/system.h is dead.

In MODULES.html.sh, the xstrndup module would belong in section
  Extra functions based on ANSI C 89
    String handling <string.h>
