ns32k_get_enter_addr, sign_extend): Restore functions mysteriously
deleted.
* ns32knbsd-nat.c: New (?) file to support fetching and storing
registers on NetBSD hosts.
* nbsd.mh (NATDEPFILES): put ns32knbsd-nat.o instead of
ns32k-nat.o
* ns32km3-nat.c (reg_offset): Get order of floating point
registers correct. Add extra 32382 register offsets.
(REG_ADDRESS): define to point at correct part of thread
state. Use calls to "warning" instead of "message".
* tm-nbsd.h, tm-ns32km3.h (REGISTER_NAMES, NUM_REGS,
REGISTER_BYTES, REGISTER_BYTE): redefine allowing for 32382
fpu registers.

automake/autoconf.

to check environment.
automake/autoconfiscate rdi-share. We don't use the checks that autoconf
provides too much for now, but it'll be easier to use them if any problems
crop up in the future. (rdi-share/ is foreign code and it probably isn't
worth spending any more time than necessary messing with it.)
* gdbtk.c: (gdb_trace_status) new function.
(gdbtk_init) added command "gdb_is_tracing".
(tracepoint_notify) added passcount information.
* tracepoint.c (trace_status_command): Recognize a boolean return
value from the stub to indicate whether trace experiment is
running. Export this value as a global state variable

a '-' can later be changed to have one.
* config/d10v/d10v.mt config/d30v/d30v.mt config/m32r/m32r.mt
config/mn10200/mn10200.mt config/mn10300/mn10300.mt : Remove -lm
from SIM. This prevents dependency checking of -lm (under NT
native builds). (It is automatically added by configure if it
exists.)
* doc/configure mswin/configure nlm/configure
testsuite/gdb.base/configure testsuite/gdb.c++/configure
testsuite/gdb.chill/configure testsuite/gdb.disasm/configure
testsuite/gdb.stabs/configure testsuite/gdb.threads/configure:

- Keith Seitz <keiths@onions.cygnus.com>
(wait_for): Don't reset the timeout_remaining for CYGWIN32,
since we now effectively poll the serial port.
Don't reset the current_timeout, either, since this member is used
by hardwire_readchar to track the timeout and call the ui_loop_hook.
(hardwire_readchar): Poll the serial port for Cygwin32. We timeout every
second, update the UI, and loop around doing this until we have hit the real
timeout or we get data or an error. This will allow the UI to stay active
while gdb is "blocked" talking to the target.
- Martin M. Hunt <hunt@cygnus.com>
(wait_for): Do reset current_timeout
because it is only used to keep track of what the
current timeout for the scb is.

don't dump core, instead print out an error message.
* breakpoint.c
- Martin M. Hunt <hunt@cygnus.com>
Make set_raw_breakpoint, set_breakpoint_count,
and breakpoint_count non-static so they are accessible from
gdbtk.c.
(enable_breakpoint): Enable breakpoint
with same disposition instead of changing all breakpoints
to donttouch.
* annotate.h
- Keith Seitz <keiths@onions.cygnus.com>
Add declarations for annotation hooks.
* annotate.c
- Keith Seitz <keiths@onions.cygnus.com>

o When MAINLINE (reading main objectfile and need to
clear out old data), change elfread.c so that the
psymbol table is emptied once (in elf_symfile_read)
instead of multiple times in each *_read_psymtab
function.
o For elf_symfile_read, load dwarf2 symbols last

o In mdebug_psymtab_read, delete check to see if
symbols for current source file already loaded.
Test doesn't work for .h files. Above change
