0.13:
  add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
  make diet not include the linker safeguard stuff when preprocessing
  Olaf: port to S/390!
  me: fix vfork (it was put into dietlibc.a twice)
  res_query did not initialize last
  diet (not diet-dyn, of course) now adds -static to the gcc command line
  fixed fflush on input streams (tic from ncurses exposed this)
  duh, there is an alarm system call, too, so we use it and not setitimer
  fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
  rewrote __dtostr (it also has one more argument now)
  Thanks to Erik Troan for bringing these to my attention:
    make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
    fix strncat for the case where n == 0 (security implications?)
    fix bsearch (it didn't find the very last element in the array, same
      bug in both the C and the i386 assembly version).
    fixed FNM_PATHNAME in fnmatch
  fix brk (the syscall was documented incorrectly in the Linux man page)
    Thanks, Thomas Ogrisegg!
  added negated character classes to fnmatch (not required by POSIX)
  make the utmp routines open utmp read-only if read-write doesn't work.
  remove syscalls.c directory, it is obsolete now with unified syscalls
