These errors are caused by following header issues on hpux:

/mnt/gnu/gcc/objdir/./gcc/include-fixed/sys/types.h:
   typedef struct _physadr { intptr_t r[1]; } *physadr;

/mnt/gnu/gcc/objdir/./gcc/include-fixed/stdlib.h:
_NAMESPACE_STD_START
         inline int abs(int d) { return (d>0)?d:-d; }
_NAMESPACE_STD_END

Probably, the use of `r' and `d' in the above circumstances is not a
problem.  So, I think the test should be adjusted as on AIX.  See attached
fix.
