* symfile.c (clear_symtab_users_once, cashier_psymtab,
free_named_symtabs): Move these routines from symmisc.c.
(free_symtab): Make non-static.
* symmisc.c (same): same.
* symtab.c (free_symtab): Declare as exported void fn now.
* dbxread.c (end_symtab, end_psymtab): Change comments.
(initialize_dbxread): Call dbx_new_init() in case the first
command is add-symbols.
* target.c (dummy_target): Permit add_syms_addr_command.

Permit symbols to be superseded when new symbol files have
been read in, particularly for VxWorks.
* dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
to the main file, as well as to include files. Also, put global
functions into the global psymtab, to make "i fun" work.
(end_psymtab): Free named symtabs and psymtabs for a file, once a
new psymtab for it has been read.
* coffread.c (end_psymtab): Free named symtabs and psymtabs for
a file, once a new symtab has been read for it.
* mipsread.c: FIXME. We need to do the same for MIPS, but it
looks harder to determine the top-level block before it's been
queued to the psymtab list.
* symfile.c (symbol_file_add): Use filtered printing and wrap it.
If we have wiped out any old symbol tables, clean up at end of
symbol reading.
(symbol_file_command): Don't reference symfile_fns if it's zero.
* symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
defines for the blocks of a blockvector that contain global and
file-static symbols and the first of the smaller scope contours.
* symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
decode_line_1, make_symbol_completion_list): Use the above.
* coffread.c (end_symtab, patch_opaque_types): Ditto.
* dbxread.c (end_symtab): Ditto.
* expread.y (block): Ditto.
* mipsread.c (throughout): Ditto.
* symmisc.c (free_named_symtabs): Ditto.
* symtab.c (list_symbols): Process the first symbol of the
static psymbols list.
(types_info): Restore this function from its untimely #if 0.
It's not perfect, but it is better than nothing.
(_initialize_symtab): Restore "info types".

* m68k-stub.c: Remote stub for 680x0's, created from
rem-m68k.shar (which is removed).
* nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
Remove RCS log stuff now that we use CVS and it blows our diffs.
Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
* symmisc.c (free_named_symtab): Make it work, in its current
kludgy fashion. Change result to indicate if we blew away bkpts.
* dbxread.c (end_symtab): Accumulate result from
free_named_symtab and print warning if we blew user's state.
* symfile.h: free_named_symtab now returns an int.
Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
* dbxread.c (dbx_symfile_read): Initialize psymbol list if this
