autoconf yet.

Looks like a big change, but it is really just a lot of small stuff.
In the cases where GCC was flagging a possible use-before-initialized
warning on variables, it turned out that these were being used properly
but GCC couldn't see that.

for `watchdog' variable. This allows the user to put an upper
limit on the amount of time that GDB will wait for the target to
return from a step or continue operation. This will primarily be
used for the testsuite, where it is difficult to come up with a
reasonable timeout for things like function calls, which can take
as long as three minutes under some circumstances. If the
watchdog timer expires, GDB will generate an error that looks like
`Watchdog has expired.', and will detach from the target.
* remote-mips.c (mips_open): Setup initial frame from target.
Print it out so that user is told where the program is stopped
when they attach.

download command.
* ser-tcp.c (tcp_open): Retry connection if we get ECONNREFUSED.
* serial.c serial.h (serial_open serial_fdopen serial_close):
Allow users to open the same device multiple times. They all get

multiple active targets use the same device (for download and
debug).
* sparcl-tdep.c: Keep #include <unistd.h> away from GO32.
* target.c: Add `targetdebug' variable. If this is non-zero,
then a special target is put at the top of the target stack which

and results printed out.
target.
* defs.h (enum language): Add language_asm.
* findvar.c (read_register_bytes read_register_gen
write_register_bytes read_register read_register_pid
write_register write_register_pid supply_register): Move multi-
thread handling down into these routines. Create XXX_pid routines
that allow register references to specify the pid.
* findvar.c infcmd.c (read_pc read_pc_pid write_pc write_pc_pid
read_sp write_sp read_fp write_fp): Move these routines from
infcmd to findvar to centralize the whole mess.
* i386-nlmstub.c: Portability fixes.

to override it. Remove PIDGET gubbish, it's no longer necessary.
* infrun.c (wait_for_inferior): Put registers_changed() before
target_wait() to speed up remote debugging.
* Replace code that reads registers from other threads with much
nicer looking new function calls (see changes to findvar.c).
* Don't skip prologues if debugging assembly source.
* lynx-nat.c (child_resume): Lynx now needs it's own version of
child_resume to handle multi-thread debugging properly.
* remote.c: Add O response to get console output from target.
* (readchar): Add timeout parameter. Handle SERIAL_EOF and
SERIAL_ERROR here to simplify callers.
* Change static var timeout to remote_timeout.
* (fromhex): Remove unnecessary return -1 at end of routine.
* (remote_wait): Turn this into a big switch statement. Add
support for O response.
* (putpkt): Remove unnecessary handling of SERIAL_EOF/ERROR.
* (getpkt): Split getpkt into two parts. read_frame deals with
all formatting issues, run-length encoding, and framing. getpkt
now handles error recovery, and frame detection.
* ser-tcp.c (tcp_readchar): Handle EINTR from read().
* ser-unix.c (hardwire_raw): Set CLOCAL so that we ignore modem
control. (hardwire_readchar): Handle EINTR from read().
* symfile.c (deduce_language_from_filename): Add support for .s
files.
* config/nm-lynx.h: Define CHILD_WAIT so that lynx-nat.c can
override infptrace's child_wait.
* config/rs6000/rs6000lynx.mh: Use xm-rs6000ly.h & nm-rs6000ly.h
instead of XXXlynx.h.
* config/rs6000/rs6000lynx.mt: Use tm-rs6000ly.h instead of
tm-rs6000lynx.h.
* nlm/gdbserve.c: Portability fixes.
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.
* inflow.c, ser-unix.c, ser-go32.c, ser-tcp.c, serial.h,
terminal.h: Move all the process group stuff back to inflow.c;
