WUR-REPORT

   1 <unistd.h>:
   2
   3 lssek:   Probably should be __wur but lseek(fd,SEEK_SET,0) will succeed if
   4          the descriptor is fine.
   5 lseek64: same
   6
   7 <stdio.h>:
   8
   9 setvbuf:   if stream and buffer are fine and other parameters constant,
  10            it cannot really fail.
  11 fseek:     see lseek
  12 fseeko:    likewise
  13 fgetpos:   similarly
  14 fsetpos:   likewise
  15
  16
  17 <stdlib.h>:
  18
  19 atexit:    it is guaranteed that a certain number of handlers can be
  20            registered, so some calls might need not be checked
  21 on_exit:   same
  22 random functions:  one might want to discard a number of results.  In any
  23            case, no security problem
  24
  25
  26 putenv:    probably SHOULD be marked, but we'll wait a bit.
  27 setenv:    likewise
  28 unsetenv:  likewise
  29 clearenv:  likewise
  30
  31 mbstowcs:  probably SHOULD be marked
  32 wcstombs:  likewise
  33
  34 ptsname_r: probably SHOULD be marked
