* breakpoint.c (describe_other_breakpoints),
symmisc.c (dump_symtab, print_symbol):
Use filtered not unfiltered I/O.
(remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
just run gdb under a debugger for this (and it had problems with
printing addresses, how to print b->shadow, etc.).
* buildsym.c (make_blockvector), core.c (memory_error),
exec.c (print_section_info), maint.c (print_section_table),
mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,

struct/union/enums and typedefs.
* partial-stab.h (case N_BINCL): Update psymtab_language
as appropriate when changing subfiles.
(case N_SOL): Update psymtab_language as appropriate when
changing subfiles. Add typedef for structs, unions, and enums
when processing C++ files.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.

Change all printf formats from %x to %lx if outputting an address.
Change la_*_format to use long format.

argument, change all callers.
* coffread.c (read_coff_symtab): Remove superfluous cast for
complaint output.
* dbxread.c (end_psymtab): Cast MSYMBOL_INFO to long, not int.
* findvar.c, value.h (write_register): Change register value to long.
* gdbtypes.h (struct type): Change `bitsize' to long as

CORE_ADDR for SETUP_ARBITRARY_FRAME.

if INLINE_ADD_PSYMBOL is not true.
* symfile.h (INLINE_ADD_PSYMBOL): Default to true if not set.
* symfile.h (ADD_PSYMBOL_*): Add language and objfile parameters.
Add code to demangle and cache C++ symbol names. Use macro form
