use the same rule for ss_err.h and ss_err.c, else `make -jN' would
run the rule twice concurrently. Don't put ss_err.c out of order

for plain `make'.
Don't put a non-generated file in CLEANFILES.

mlock, mmap, mprotect, msync, munlock, and munmap are defined by
POSIX as taking void *. The const modifier has been added to
mlock, munlock, and mprotect as the standard dictates.
minherit comes from OpenBSD and has been updated to conform with
their recent change to void *.
madvise and mincore are not defined by POSIX, but their arguments
have been modified to be consistent with the POSIX-defined functions.
mincore takes a const pointer, but madvise does not due to the

instead of Singe Unix, thanx Bruce for explaining, I am not realize
standards war was there.
But now, fix n == 0 case to not return error and fix check for too
big n.
Things left to do: check for overflow in arguments.
Final word is Bruce's quote:
C9x specifies the BSD4.4-Lite behaviour:
[#3] ... Thus, the
null-terminated output has been completely written if and
only if the returned value is less than n.
It means that if we not have any null-terminated output as for n == 0
we can't return value less than n, so we forced to return value
equal to n i.e. 0
The next good thing is glibc compatibility, of course.
2) Do check for too big n in machine-independent way.
3) Minor optimization assuming EOF is < 0
The main argument is that it is impossible to determine if %n evaluated or not
when snprintf return 0, because it can happens for both n == 0 and n == 1.
Although EOF here is good indication of the end of process, if n is
decreased in the loop...
Since it is already supposed in many places that EOF *is* negative, f.e.
from Single Unix specs for snprintf
"return ... a negative value if an output error was encountered"
this not makes situation worse.
to pass not more than buffer size to %n agrument, old variant
always assume infinite buffer.
%n is for actually transmitted characters, not for planned ones.
"return the number of bytes needed, rather the number used"
According to Single Unix specs:
Upon successful completion, these functions return the number of bytes
transmitted excluding the terminating null
1) if buffer size is smaller than arguments size, return buffer
size, not arguments size as before.
2) if buffer size is 0, return 0, not EOF as before.
(now it is compatible with Linux and Apache implementations too).
NOTE: Single Unix specs says:
If the value of n {buffer size} is zero on a call to snprintf(), an
unspecified value less than 1 is returned.
It means we can't return EOF since EOF can take *any* value in general
not especially < 1. Better variant will be return -1 (it is less then
1 and different with n == 1 case) but -1 value is already occuped by
EOF in our implementation, so we can't distinguish true IO error
in that case. So 0 here is only possible case still conforming
to Single Unix specs.

a malloc. The signal handler creates a thread which requires a malloc...
For now, the only thing to do is to block signals. When we move user
pthreads to use the kernel threads, mutexes will be implemented in kernel
space and then malloc can revert.

to the same version numbers as 2.2.x.
The problem with the way things were was:
- if you took a 2.2.x binary, it either wouldn't run on -current or
if you had the old -current version of libtermcap.so.2.1 then it could
potentially be a security problem.
- the alternative is to start a compat22 tree dist for -current with a
uuencoded binary. This makefile hack is less cost.
libtermcap.so.3.0 is provided via /usr/lib/compat to avoid transition
problems.
a similar way to libc. Sigh. This is not pretty but seems to work.
Somthing like this was needed in preference to bogusly bumping the major
library number here.
The syscall(SYS_issetugid) idea is originally Bruce's.
functions would return -1 and set errno to indicate the specific error.
POSIX requires that the functions return the error code as the return
value of the function instead.
on systems where long doubles are just doubles. FreeBSD hasn't
been such a system since it started using gcc-2.5 many years ago.
The fix is of low quality. It loses precision.
scanf() of long doubles doesn't seem to be used much, but gdb-4.16
uses %Lg format in its expression parser if it thinks that the
system supports printf'ing of long doubles. The symptom was that
floating point literals were usually interpreted to be 0.0.
Note this ONLY affects the function version - the macro version is always
used unless for some reason you put #undef sigismember in your code before
calling it.

Add an option to the way UFS works dependent on the SUID bit of directories
This changes makes things a whole lot simpler on systems running as
fileservers for PCs and MACS. to enable the new code you must
1/ enable option SUIDDIR on the kernel.
2/ mount the filesystem with option suiddir.
hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.
Ever since I first say the way the mount flags were used I've hated the
fact that modes, and events, internal and exported, and short-term
and long term flags are all thrown together. Finally it's annoyed me enough..
This patch to the entire FreeBSD tree adds a second mount flag word
to the mount struct. it is not exported to userspace. I have moved
some of the non exported flags over to this word. this means that we now
have 8 free bits in the mount flags. There are another two that might
well move over, but which I'm not sure about.
The only user visible change would have been in pstat -v, except
that davidg has disabled it anyhow.
I'd still like to move the state flags and the 'command' flags
apart from each other.. e.g. MNT_FORCE really doesn't have the
same semantics as MNT_RDONLY, but that's left for another day.

several categories:
- Cosmetic/mdoc changes. They don't really afect the output
at all, but having them in 2.2 will make it easier to diff the man
pages later when looking for real changes.
- Update some man pages to reflect the current 2.2 header files.
- Sort xrefs.
- A few typo fixes.
- And a few changes that actualy added text to the man page that should
be reflected in 2.2.
- Add some missing MLINKS.

partway through its attempt to decode the result structure sent by
the server. If this happens, it can leave the result partially
populated with dynamically allocated memory. In this event, the
xdr_replymsg() failure is detected and RPC_CANTDECODERES is returned,
but the memory in the partially populated result struct is not
free()d.
The end result is that memory is leaked when an RPC_CANTDECODERES
error occurs. (This condition can occur if a CLIENT * handle is created
using clntudp_bufcreate() with a receive buffer size that is too small
to handle the result sent by the server.)
Fixed by setting reply_xdrs.x_op to XDR_FREE and calling
xdr_replymsg() again to free the memory if an RPC_CANTDECODERES error
is detected.
I suspect that the clnt_tcp.c, clnt_unix.c and clnt_raw.c modules
may ha a similar problem, but I haven't duplicated the condition with
those yet.

to fail under certain circumstances.
1. In one spot, the ifr_flags member was being examined in the
wrong structure, thus it contained garbage. On a machine in which
only the loopback interface was up, this caused everything that
wanted to talk to the portmapper to fail -- a particular problem
with laptops, where the pccard ethernet interface is likely to come
up long after the attempt to start mountd, nfsd, amd, etc.
2. Compounding the above problem, get_myaddress() returned a
successful status even though it failed to find an address that it
considered good enough.
This fixes bugs in the manual handling. abs.[cS] was handled too
specially and the wrong (.c) variant for each of div.[cS], labs.[cS]
and ldiv.[cS] was added to SRCS. This caused the .c variant to be
used if `depend' was made and the .S version to be used otherwise.
The names of m-d variants are now added (manually) to MDSRCS instead
of to SRCS, and the names of all machine-independent (m-i) variants
that can reasonably be replaced by an m-d variant are now added
(manually) to MISRCS instead of to SRCS, so that a simple substitution
can be used to discard the unused m-i variants. MISRCS is potentially
all m-i sources, but the substitution is too simple to be fast, so
MISRCS should be kept reasonably small.
libc/Makefile.inc:
Do the substitution.
libc/i386/string/Makefile.inc:
Add to MDSRCS instead of to SRCS. Add the names of all sources in this
directory, but no others.
libc/string/Makefile.inc
