  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  Minix 3.1.8, mingw, MSVC 14.
  But the provided replacement is just a dummy on some of these platforms:
  Minix 3.1.8.

  Portability problems not fixed by Gnulib:
  @itemize

  This function does not behave as required by POSIX for mutexes of type
