* solib-pa64.c (pa64_solib_create_inferior_hook): Don't set
DT_HP_DEBUG_PRIVATE. Add warning if DT_HP_DEBUG_PRIVATE is not set. Revise comment. (pa64_current_sos): Remove map private warning warning. * solib-som.c: Include string.h and sys/utsname.h. (get_hpux_major_release): New function. (som_solib_create_inferior_hook): Read dynamic linker header. Warn about shared library private mapping on HP-UX 11 and later. Only force private mapping of shared libraries on HP-UX 10 and earlier. (link_map_start): Delete warning.
