It's in glibc 2.5, the fread etc declarations are followed by __wur and
sys/cdefs.h contains the following code:


/* If fortification mode, we warn about unused results of certain
   function calls which can lead to problems.  */
#if __GNUC_PREREQ (3,4)
# define __attribute_warn_unused_result__ \
   __attribute__ ((__warn_unused_result__))
# if __USE_FORTIFY_LEVEL > 0
#  define __wur __attribute_warn_unused_result__
# endif
#else
# define __attribute_warn_unused_result__ /* empty */
#endif
#ifndef __wur
# define __wur /* Ignore */
#endif


 ciao

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
