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 >= 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.
