when using the egcs and gcc-devel ports, along with GCC built from stock
public FSF sources. With out this change, FreeBSD will be removed from
the list of systems GCC 3.0 must be evaluated on before release. With
the effort some of us put into getting FreeBSD on this list, we should
not turn this effort into a waste, else we might not be worth fighting
for in the future. (note that Alpha and IA-64 versions of crt{i,n}.S
are needed)
* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c.
This will allow us to switch to DWARF2 exceptions in the future, along with
staying in sync with any future GCC requirements.
* Break out our ELF branding bits into a seperate file. Currently this
is now included by our crt1.c files (since this functionality was part of
our native crtbegin.c). Later crtbrand.o will be merged in the creation
of crti.o.
getting libutil/libcrypt to work properly. I've determined that GCC
thinks it can inline all functions, including weak-symboled ones, if
it feels like it.
Create a new stub.c and move any stubs there to prevent inlining.
Thanks to jdp and William S. Duncanson for helping me finally find the
problem.

when there are no application installed signal handlers.
Correct a typo in sigwait (foo -> foo[i]).

adding a signal frame to a thread, be sure to label the context

- ftpTimeout was not honored when reading actual data, as opposed to
talking protocol
- connection caching was broken because _ftp_cached_connect() would see
the result of the transfer instead of the result of the NOOP.
- if the RETR succeeded, but an error occurred later (as can happen
when talking to a proxy), the error would not be detected.
There still remains to register an atexit(3) callback to close the cached
connection gracefully instead of just dropping it on the floor.

Bugfix: 'Keep the bit position even when the report descriptor says POP.'
Add hid_use_report_desc, hid_parse_usage_page, hid_parse_usage_in_page.
Changed iface for hid_report_size.
Add references to the newly added hardware debug register
support functions i386_clr_watch(3) and i386_set_watch(3).

thread switches should be on par with that under scheduler
activations.
o Timing is achieved through the use of a fixed interval
timer (ITIMER_PROF) to count scheduling ticks instead
of retrieving the time-of-day upon every thread switch
and calculating elapsed real time.
o Polling for I/O readiness is performed once for each
scheduling tick instead of every thread switch.
o The non-signal saving/restoring versions of setjmp/longjmp
are used to save and restore thread contexts. This may
allow the removal of _THREAD_SAFE macros from setjmp()
and longjmp() - needs more investigation.
Change signal handling so that signals are handled in the
context of the thread that is receiving the signal. When
signals are dispatched to a thread, a special signal handling
frame is created on top of the target threads stack. The
frame contains the threads saved state information and a new
context in which the thread can run. The applications signal
handler is invoked through a wrapper routine that knows how
to restore the threads saved state and unwind to previous
frames.
Fix interruption of threads due to signals. Some states
were being improperly interrupted while other states were
not being interrupted. This should fix several PRs.
Signal handlers, which are invoked as a result of a process
signal (not by pthread_kill()), are now called with the
code (or siginfo_t if SA_SIGINFO was set in sa_flags) and
sigcontext_t as received from the process signal handler.
Modify the search for a thread to which a signal is delivered.
The search algorithm is now:
o First thread found in sigwait() with signal in wait mask.
o First thread found sigsuspend()'d on the signal.
o Current thread if signal is unmasked.
o First thread found with signal unmasked.
Collapse machine dependent support into macros defined in
pthread_private.h. These should probably eventually be moved
into separate MD files.
Change the range of settable priorities to be compliant with
POSIX (0-31). The threads library uses higher priorities
internally for real-time threads (not yet implemented) and
threads executing signal handlers. Real-time threads and
threads running signal handlers add 64 and 32, respectively,
to a threads base priority.

u_int64_t flag field, bounding the number of capabilities at 64,
but substantially cleaning up capability logic (there are currently
43 defined capabilities).
o Heads up to anyone actually using capabilities: the constant
assignments for various capabilities have been redone, so any
persistent binary capability stores (i.e., '$posix1e.cap' EA
backing files) must be recreated. If you have one of these,
you'll know about it, so if you have no idea what this means,
don't worry.
o Update libposix1e to reflect this new definition, fixing the
exposed functions that directly manipulate the flags fields.
