 Many systems provide a safe/thread-safe/reentrant variant of common
 routines, for instance for strerror(): strerror_s or strerror_r. It should
 be fine to always use the improved variant.
 The standard way is to use our own variant and to define it in libutil,
 using the system one or recoding it when it is not available...
 I propose to add to this ticket a list of such routines:
  - strerror
