0.22:
  fix i386 libm
  fix netinet/ip_icmp.h (Rui Prior)
  make strings.h susv3 compliant (Gunnar Ritter)
  remove stdio dependence in abort
  fix truncate64, ftruncate64 (Luc Van Oostenryck and Yuri Kozlov)
  fix and improve erand48() (Luc Van Oostenryck)
  fix realpath for non-existant directories (Gergely Nagy and Gerrit Pape)
  fix DNS timeout and IPv6 socket reuse
  strtoul now accepts "-1" as well (Thomas Ogrisegg)
  add i386 strcasecmp and __ltostr (Thomas Ogrisegg)
  add killpg prototype (Luc Van Oostenryck)
  remove some compiler warnings (Luc Van Oostenryck)
  better rand() from Knuth's TAOCP (Luc Van Oostenryck)
  fix unified x86_64 unified syscall 64-bit return value issue (Gwenole)
  the getdents64 emulation was broken and repairing it opened a can of
    worms.  So I ripped it out.  I also changed the readdir64 emulation
    to work if there is no getdents64.
  fix ia64 start.S (Thanks to Volker Birk for an account on his ia64 box)
  many ia64 fixes (waitpid, nice, fork, vfork, time, utime ...)
  More fixes from Gwenole (printf %p only printed the last 32 bits, I
    botched the getdents64 #ifdefs, we violated the x86_64 ABI)
  change signal() to do as glibc does
  remove a few more warnings
  add new 2.5 syscall #defines
  add epoll_create, epoll_ctl and epoll_wait
  the new x86 syscall numbers exceed 255, breaking our %al optimization
    I worked around it with conditional assembly in cpp macros.  Ugh.
  more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
    the instruction before the syscall to be a load immediate)
  fix fread() from a pipe (oops, tried to lseek)
  #define _POSIX_VDISABLE in termios.h (Laurent Bercot)
  two *printf fixes (Gernot Tenchio)
  add nan and +-inf handling in __dtostr
  add _SC_NGROUPS_MAX support to sysconf (Felix J. Ogris)
  make assert() use expect(), slight optimization
  add i386 vfork (Thomas Ogrisegg)
  fix SA_NODEFER on sparc (Gerrit Pape, Thomas Bader)
  fix sin, cos and __dtostr (Gernot Tenchio)
  add /dev/epoll ioctl constants to sys/ioctl.h
  add linux/eventpoll.h for /dev/epoll
  fix lseek64 on 64-bit architectures
  Olaf: fix x86_64 start-code (we have reg-args)
    fixing some broken macros in sparc32-code (.udiv,.urem)
    adding strndup (GNU Extension)
  fix glob strncpy (R.L. Horn)
  fix regfree (Uwe Ohse)
  fix puts in full stdio mode (would omit \n)
  fix wrong types on powerpc, broke *stat (Gerrit Pape)
  allow more than 64k in i386 memchr (Karsten Scheibler)
  make strftime work it WANT_TZFILE_PARSER is not set (Gwenole Beauchesne)
  build parisc on parisc64, change libgcc link order on sparc (Gerrit Pape)
