Description: when compiling with -D_FORTIFY_SOURCE=2, the compiler will
 generate warn-unused-results notifications for several functions.  It
 is not sensible to do this for fwrite() since it is frequently unchecked
 and may not fail until fclose() which is not marked with __wur, making
 the fwrite() check noisy and pointless.
