GCC that we are using
gcc version 4.9.2 (Debian 4.9.2-10)

Glibc: 2.19-18+deb8u1:

The offending code in unistd.h:

extern ssize_t write (int __fd, const void *__buf, size_t __n) __wur;

./x86_64-linux-gnu/sys/cdefs.h:#  define __wur
__attribute_warn_unused_result__

As to why other people are not seeing it.  I would imagine not everyone is
running with -Wall and -Werror turned on at the same time as part of a
build.
