   According to the ISO C standard, the result of calling
 fflush() on anything other than an output or update stream
 is undefined.  FreeBSD's behaviour here is consequently
 correct; any behaviour would be correct.
   Programs which rely upon fflush() not returning an error
 when passed a file which is opened read-only are broken,
 and should be fixed.
