The same happen on HP/UX 11.22 The manual page for sleep(3) on HP/UX
says that 'seconds must be less than 2^31'.

Solaris 8 behaves differently.  It returns immediately with ret = 0:

  % ./a.out
  Ret is :0
  %

Looking at
<URL:http://www.opengroup.org/onlinepubs/007904975/functions/sleep.html>,
it is hard to tell if this is supposed to work or not.  I guess it
should.
