I don't know anything about octave, but what has changed is that newlib
is finally introducing BSD-like visibility macros.  The pwd.h header now
contains this:

  #if __XSI_VISIBLE >=3D 500
  struct passwd   *getpwent (void);
  void             setpwent (void);
  void             endpwent (void);
  #endif

The default settings per the sys/cdefs.h header are:

  #define __POSIX_VISIBLE         200809
  #define __XSI_VISIBLE           700
  #define __BSD_VISIBLE           1
  #define __ISO_C_VISIBLE         2011

unless your environment defines one of

  _XOPEN_SOURCE
  _POSIX_C_SOURCE
  _ANSI_SOURCE
  _C99_SOURCE
  _C11_SOURCE
  _GNU_SOURCE

Have a look at the end of /usr/include/sys/cdefs.h, it explains things.
