modern FreeBSD systems will syslog properly on older systems that
still name the logging socket "/dev/log". This includes pre-2.2
versions of FreeBSD as well as BSD/OS systems. If the connect to
"/var/run/log" fails, the function now tries to connect to
"/dev/log" as a fallback.

for scsreq_build(), the long arg list was chopped near column 80, to
no avail since the closing parentheses was put on new line by itself.
Back out a dubious Lite2 change to "optimise" getcwd() to look at $PWD
because it's potentially dangerous (think: symlink races). Move
realpath() back to it's original location, and remove getcwd_physical()
by renaming it back to getcwd() and zapping the original getcwd wrapper.

skipping white-space after 0 assignments. This fixes PR2606. The

This should be in 2.2.

previous revision. Use log10f() instead of log10(). log10f() is
currently slightly slower than log10() on P5's, but it is potentially
significantly faster.
Fixed declaration of the C function used in the (unused?) KR_headers
case.
avoid easily avoidable loss of precision when |x| is nearly 1.
Extended (64-bit) precision only moves the meaning of "nearly" here.
This probably could be done better by splitting up the range into
|x| <= 0.5 and |x| > 0.5 like the C version. However, ucbtest
does't report any errors in this version. Perhaps the C version
should be used anyway. It's only 25% slower now on a P5, provided
the C version of sqrt() isn't used, and the C version could be
optimized better.

etc/make.conf:
Nuked HAVE_FPU option.
lib/msun/Makefile:
Always build the i387 objects. Copy the i387 source files at build
time so that the i387 objects have different names. This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.
lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.
lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.
sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization. The PIC case is
messy. The old i387 entry points are renamed. Renaming is easier
here because the names are given by macro expansions.
log10(x) = log10e * log(x). The formula would work if the RHS were
evaluated in extended precision with an extended precision log().
This actually happened with the i387 log() because it returns excess
precision.

This defeats the point of log1p(). ucbtest reports errors of +-5e+15
ULPs. A correct version would use the i387 fyl2xp1 instruction for
small x and maybe scale to small x. The C version does the scaling
reasonably efficiently, and fyl2px1 is slow (at least on P5s), so not
much is lost by always using the C version (only 25% for small x even
with the broken i387 version; 50% for large x).

Added missing `.text' to START_ENTRY so that ENTRY() works when

I notice info(1) has some problems moving back and forth through the

Sheepishly use sigaction() like a good boy and make timeouts actually do

Also pass errors out more effectively so that fetch(1) actually understands

- Use MAP_FAILED instead of the constant -1 to indicate

The `install' target should only be overridden when the default one would
do something wrong and you're too lazy to fix the default one.
Restore the clamp on the return value from rpc_dtablesize().. Some programs
(eg: ypserv) use this as an indication of how large svc_fdset is in their
hand-rolled svc_run() loops. The svc_fdset table is maintained by the
rpc library explicitly for compatability with such programs. (It uses
a different variable-sized bitmap itself internally)

Obtained from: a diff of FreeBSD vs. OpenBSD/NetBSD rpc code.
Note, there was a nasty bug with our old code here. It would trash the
stack if a fd > 31 was passed in. It was using a "long" as though it
was an "fd_set", ie: it was assuming that a long was 256 bits wide. :-(
This has been lurking here for a while, since the FD_SETSIZE #ifdef's
were first implemented.

RELENG_2_2!
This is part#2 of the previous commit to src/lib/libc/net to contain the
potential damage.
This provides stubs so that binaries linked in 2.2 will run on 3.0
needed, as he discovered when he tried to run vi. :-]
These files used to be stubs which used #ifdef PIC to decide whether to
use the real dlopen() version or the stub version from the src/contrib/tcl
sources. Now, with the our stubs gone, the .PATH directive causes them to
be compiled directly from src/contrib/tcl/{unix,generic}. You might need
to rebuild your depend rules though as they may have stale paths.
Also, this is a generated file. This should not have been edited here.
also add the missing declaration of forkpty() to libutil.h.
Btw., the calling interface for login(3) is crude. Some better
abstraction is needed, perhaps similar to logwtmp(3).
2.2 candidate, but i'll wait for the spelling police first. :)
- the .gz files are no longer used as intermediate files, it's in a pipe
now. (gunzip normally deleted them anyway, but this should not hurt)
- I accidently left a -p arg to install from testing. Bruce says it should
be ${COPY} instead, but almost everything else in the tree uses plain -c
anyway.
- Use "LINKS=" or two identical files are installed sepeately instead of
as links (doh!)
- Use "LIB..." instead of "BIN..." for install permissions. Note that we
still use bsd.prog.mk, not bsd.lib.mk because bsd.lib.mk has problems
(it can't install a library unless it compiles it).
- Define LIBCOMPATDIR in Makefile.inc instead of using BINDIR.

just return errors. This removes the need for awful hacks like that in
our build of libtcl which would get link errors when linked static.
John Polstra once mentioned that this was on his "todo" list.
Note that one can use:
cc -Wl,-Bstatic -o foo foo.o
and get an executable that has it's libraries statically linked, but has
a fully functional runtime linker so the executable can call dlopen() and
have it work. (I've tested this)
- getpwent:
o adjunctbuf should be NUL terminated after copying
o _pw_breakout_yp() needs to know the length of the buffer returned
from YP so it can properly NUL terminate its local buffer.
- getgrent:
o YP buffers should be YPMAXRECORD + 2 bytes long and NUL terminated.
(Previously they were hardcoded to 1024 bytes.)
- getnetgrent:
o YP data should be copied with snprintf(), not sprintf()
These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.
- getservent:
o put _yp_check() proto under #ifdef YP where it belongs
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- gethostbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long
- getnetbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- ether_addr:
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
but it happens that BUFSIZ == YPMAXRECORD.
- gethostbydns:
o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)
These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.
