Further hpux libstdc++-v3 cleanups

[law at redhat dot com]

	* config/os/hpux/bits/os_defines.h: Do not include <_sys/inttypes.h>.
	Twiddle return types for strtoll and strtoull to avoid using
	intmax_t and uintmax-t.

     <inttypes.h>.  Ugh.
  
     <inttypes.h> defines a variety of things, some of which we 
!    probably do not want.  So we just provide prototypes for
!    the functions we care about here.
  
!    However, to do that, we must include <sys/_inttypes.h> to get
!    intmax_t and uintmax_t.  Luckily <sys/_inttypes.h> looks a
!    lot cleaner as far as namespace pollution is concerned. 
  
     We also force _GLIBCPP_USE_LONG_LONG here so that we don't have
     to bastardize configure to deal with this sillyness.  */

!    Luckily we can just declare strtoll and strtoull with the
