uses. Make static.
(PT_READ_U, PT_WRITE_U, PTRACE_XFER_TYPE): Define if needed.
Include sys/ptrace.h.

* config/powerpc/linux.mh (NATDEPFILES): Delete core-aout.o.

(print_objfile_section_info): New function.
(_initialize_maint_commands): Add help for new features.
* maint.c (maintenance_info_sections): Pass string argument to
print_section_table, so that it can be used to select sections.
(print_section_table): Change PTR to void *. Look at string arg
to select sections by name and by flag attributes.

(print_bfd_flags): New function.
(struct remote_state): Rename field g_packet to regs;
(free_remote_state): Update.
(init_remote_state): Add pseudo-registers to table. Initialize
in_g_packet. Drop sentinal from table.
(packet_reg_from_regnum, packet_reg_from_pnum): Update.
(remote_fetch_registers): Handle registers not in the g-packet.
(remote_store_registers): Ditto.
out of the return address register, cache that in the frame's
extra info, just as if we'd gotten it from the saved regs array;
that way, it's not a lie to set the saved_pc_valid flag.
* gdbarch.c, gdbarch.h: Regenerated.
* gdbtypes.c (build_gdbtypes): If TARGET_CHAR_SIGNED is zero,
set the TYPE_FLAG_UNSIGNED bit on the type.
* s390-tdep.c (s390_gdbarch_init): On the S/390, characters
are unsigned by default.
* rs6000-tdep.c (rs6000_gdbarch_init): Same for PowerPC and
RS6000.
* gdbarch.c, gdbarch.h: Regenerated.
* gdbtypes.c (build_gdbtypes): If TARGET_CHAR_SIGNED is zero,
set the TYPE_FLAG_UNSIGNED bit on the type.
* s390-tdep.c (s390_gdbarch_init): On the S/390, characters
are unsigned by default.
* rs6000-tdep.c (rs6000_gdbarch_init): Same for PowerPC and
RS6000.

safe_read_memory_integer): New functions.
* gdbcore.h (safe_read_memory_integer): Export.
* arm-tdep.c (arm_scan_prologue): Use safe_read_memory_integer,
to read the frame value, to capture calls to error().

number.
* s390-tdep.c (s390_register_virtual_type): Replace clever but
incorrect range comparison with correct, legible equivalent.
backtracing in a called function.
* gdb.base/constvars.exp: Only set lang to C++ if we're
compiling the test with HP's compilers.
* gdb.base/volatile.exp: Similarly.
