Various changes to get linker working again for a.out:
* don't set/adjust section file positions or vmas more than once
* use correct page size and segment size when calculating them
* deal with some variations in a.out implementations
Tested on sun4 and sun4->sun3 so far, will be testing further but
needed to get wider exposure&testing. See ChangeLog for details.
Also:
* coffcode.h (coff_write_relocs): Write out swapped reloc, not
pre-swapped version.
* hosts/sparc.h (abort, exit): Hide these names if compiling with
gcc version 2, to avoid warnings.

C++ lookups fail, print possibly helpful hint about completion.

for static data members.
* dbxread.c (dbx_psymtab_to_symtab_1): Fix prototype.
* config/ncr3000.mh (INSTALL): Don't use /usr/ucb/install,
it's broken on ncr3000's.
Change 'modifier' to char from unsigned char. Cast single use
that needs to be unsigned char.
* symtab.h (SYMBOL_BASEREG_VALID): Explain disabling.
* utils.c (strdup_demangled): Add function.

when appropriate. Fix supplied by Peter Schauer.

* symtab.h: Disable SYMBOL_BASEREG_VALID until it works.
* dbxread.c (dbx_psymtab_to_symtab_1): Renamed from
psymtab_to_symtab_1. Use current psymtab's sym_offset and symbol_size,
rather than the one for the first file in the dependency chain.
ugly changes in signal blocking macro. Use them throughout,
reducing #ifdef HAVE_POSIX_SIGNALS and HAVE_BSD_SIGNALS clutter
significantly. Make all such places use POSIX if available,
to avoid losing with poor `sigsetmask' emulation from libiberty.
set. Don't reset our own texthigh, or dependency-only pst's, in
scanning all the rest of the psymtabs.
(process_one_symbol): Fix comments around N_OBJ, N_OPT, N_UNDF.
* buildsym.h (N_UNDF): Improve comments.

an additional per-symbol value.

* frame.h (FRAME_GET_BASEREG_VALUE): Provide default definition.
* findvar.c (read_var_value): Use SYMBOL_BASEREG if valid.

* symmisc.c (print_symbol): Use SYMBOL_BASEREG if valid.
extra info in the minimal symbol.
(elf_symtab_read): The extra info is the size of an ELF object,
which was kludged to us in the `udata' field of the BFD symbol.
Gag me with a crowbar...
(elf_symfile_read): Keep track of both the absolute load address,
and the offset between load addr and symbols. Handle STABS as
well as DWARF sections, passing the absolute load address to
elfstab_build_psymtabs.
* objfiles.c (free_objfile): Eliminate storage leaks. Contributed
by <Peter.Schauer@regent.e-technik.tu-muenchen.dbp.de>.
* symfile.c (symfile_bfd_open): Comment where name is freed.
* symmisc.c (extend_psymbol_list): Comment where list is freed.
Add symbol_size and file offsets to struct symloc.
Add static symbol_table_offset, string_table_offset,
file_string_table_offset, next_file_string_table_offset,
last_function_name.
(add_old_header_file): Convert error() to complain()t.
(dbx_symfile_read): Get symbol size via the objfile.
Also get symbol_table_offset.
(dbx_symfile_init): Record symbol size and count via the objfile.
(dbx_next_symbol_text): Always add file_string_table_offset when
accessing string table.
(read_dbx_symtab): Initialize file_string_table_offset to 0.
(SET_NAMESTRING): Use the offset.
(end_psymtab): Large kludge to determine addresses where source
files start and end (for the psymtab header).
(psymtab_to_symtab_1): Set file_string_table_offset before reading.
Get this, symbol size, and symbol offset, from psymtab.

Patch up last_source_start_addr if zero in N_SO.
(process_one_symbol): Add variable function_start_offset.

(elfstab_build_psymtabs): New function to read stabs out of

(N_OBJ, N_OPT): Ignore.
('f', 'F'): Save last function name.
