when trying to store the year in a signed int. The maximum time_t on ia64
is around 292 billion years in the future, but 'int' and struct tm.tm_year
can only represent then ext 2.1 billion years or so.
This solves the problem of mktime/localtime looping on ia64. Unfortunately,
the standards say that tm_year is an 'int', so we are still stuck with a
y2147483647 bug. bash2's configure script looks for bugs in mktime() and
fails on ia64 because of this. However, mktime() on FreeBSD fails the test
normally anyway so this is no big loss.
This change does not affect any other platforms besides ia64.

been repo-copied from src/lib/libc/uuid to src/include. Update the
makefiles.
While in src/include/Makefile, reformat and resort INCS. Reverting
the functional change only involves removing uuid.h.

I've no idea if this is the right behavior for the library, but this
at least fixes the build, and matches what seems to be alfred's intent
in the commit message for 1.19.
sysconf.c:
Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0'
return value from the kernel sysctl.
vfs_aio.c:
Make aio reset its configuration parameters to -1 after unloading
instead of 0.
posix4_mib.c:
Initialize the aio configuration parameters to -1
to indicate that it is not loaded.
Add a facility (p31b_iscfg()) to determine if a posix4 facility has been
initialized to avoid having to re-order the SYSINITs.
Use p31b_iscfg() to determine if aio has had a chance to run yet which
is likely if it is compiled into the kernel and avoid spamming its
values.
Introduce a macro P31B_VALID() instead of doing the same comparison over
and over.
posix4.h:
Prototype p31b_iscfg().
libc. I want to keep these in some version for the thread
library/ies, but don't know whether to have them repo-copied
to libc_r or renamed and kept in libc.
Change the name of an alpha macro that was changed with the
system call commit.
subsystems capabilities:
_SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX
_SC_AIO_MAX returns the default _POSIX_AIO_MAX
_SC_AIO_PRIO_DELTA_MAX returns the default of 0
Without these adjustments the values returned are -1 even when the
aio side of the kernel returns '0' for them which is incorrect.

architecture, mainly to avoid getting a SIGFPE signal sent
when calling strtod(3) with certain input.
The SIGFPE has been sent because the code was not aware that
a Gradual Underflow is handled in software via traps on the
Alpha architecture, but is not implemented in our Alpha kernel
layer.
With `Sudden_Underflow' defined, strtod(3) should not depend
on Gradual Underflow and adjust its calculations accordingly,
which means that other, more subtle errors than the sending of
SIGFPE could be solved by this.

caused by dynamic PAM modules that call openlog(3) and closelog(3),
e.g. ports/security/pam_pwdfile.
What happened here is that the module first registered its "ident"
with openlog(3), then PAM library unloaded module with dlclose(3),
and the next call to syslog(3) resulted in SIGSEGV.

o Remove the unwanted smartness in _longjmp() where it compares
the current ar.bspstore with the saved ar.bspstore and restores
ar.rnat based on it. This either avoids saving ar.rnat in the
jmp_buf or is the consequence of not saving ar.rnat. All this
complexity breaks libc_r where we use longjmp() to switch to
different threads and the current ar.bspstore has no relation
to the saved ar.bspstore. Thus: we save ar.rnat in setjmp()
and simply restore ar.bspstore and ar.rnat in longjmp().
This code needs a cleanup.
entries in the table being stubs. While I'm here, add macros to
auto-generate the stubs. A conforming threads library can override
the stub routines by filling in the jump table.
Add some entries to namespace.h and sync un-namespace.h to it.
Also add a comment to remind folks to update un-namespace.h
when changing namespace.h.
Don't force 16-byte alignment at run-time. Do it at compile-time.
This saves us the pointer fiddling by the setjmp functions and
reduces complexity. While here, increase the jmp_buf by 16 bytes
to an even 512 bytes. Coincidentally, due to the way alignment
was handled prior to this change, the jmp_buf has not changed in
size, but only in how the space is used. Prior to this change
the 16 bytes were reserved for enforcing alignment; now they are
reserved by us for future extensions.
Therefore, this ABI breaker is relatively save: the failure is
always an alignment trap.
namely uuidgen(1), uuidgen(2) and uuid(3), the following division
has been choosen:
uuidgen(1) A description of the command line utility,
and other user oriented UUID information.
uuidgen(2) A mostly technical description of UUIDs.
uuid(3) A description of the functions and other
programmer oriented UUID information.
According to the division: add more technical contents.

to be static for 5.0. I may remove this for 5.1 or 5.2. No more
binaries or libarires will be generated with __sF starting as of
yesterday. Originally the plan had been to eliminate this for 5.0,
but we didn't get the __std{in,out,err}p changes merged into -stable
until yesterday (rather than in September 2001 like it should have
been). Given that didn't happen on time, we can't do the other part
of the scheme now.
