ioctl, it indicates that the process has exited.
an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
* defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
If BFD64, make a LONGEST a BFD_HOST_64_BIT.
* defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
always just check against INT_MIN and INT_MAX (this also fixes things
if sizeof (long) > sizeof (int), e.g. Alpha).

ourself based on sizeof (LONGEST) rather than relying on
BUILTIN_TYPE_LONGEST. The point is that we don't depend on
CC_HAS_LONG_LONG anymore.
* valprint.c (val_print_type_code_int): Just call
extract_unsigned_integer directly, rather than going through
unpack_long.

change 'g' size to 'w' for integers. print_scalar_formatted handles
printing huge integers well enough, thank you.
* gdbtypes.c (check_stub_type): On TYPE_FLAG_TARGET_STUB, do
what cleanup_undefined_types does for arrays, except we clear
TYPE_FLAG_TARGET_STUB if we fix up the type.
* stabsread.c (cleanup_undefined_types): Add comments about how
doing arrays here is no longer the clean way to do it.
(read_array_type): Set TYPE_FLAG_TARGET_STUB as well as calling
add_undefined_type.

outside switch so it happens for all type codes.
* cp-valprint.c (cp_print_value_fields): Recurse to val_print,
instead of c_val_print, so that check_stub_type gets called.
* gdbtypes.h, gdbtypes.c, m2-lang.c, ch-lang.c, c-lang.c: Remove
TYPE_FLAG_SIGNED. It was inconsistently set, never checked
(except in recursive_dump_type), and is pointless.
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.
