Doing the "right thing" here is difficult, so create two ENTRY points for
each function (for example, __setjmp and setjmp are equivalent). This
isn't pretty, but it works for both aout and ELF.
libc symbol naming needs an overhaul in order to properly support function
wrapping, specifically in the case of a real libpthread, and these
duplicate entry points should be fixed as part of that overhaul.

takes an int arg and is prototyped in <string.h>. It has the opposite
interface botches to psignal(3) which takes a bogus unsigned arg but is
prototyped in the right place.
This is not the last of the interface problems for strsignal(). We
obtained it from NetBSD, but NetBSD has moved its prototype to
<unistd.h>. strsignal() should return const char *, but it returns
char * for historical reasons. NetBSD declares it as returning
__aconst char, where __aconst is normally empty but can be set to
`const' to give better error checking. glibc-2.1.1 prototypes
strsignal() in <string.h>.
lobotomized environment, say booted from a floppy with no /etc full
of password and group files, give sensible fallbacks for roots uid
and operators gid.
This might fix sysinstall.

Removed vlimit.3 and vtimes.3. Removed vlimit.c and vtimes.c from
the "MISSING" list. These were old variants of get/setrlimit() and
getrusage(), respectively, and were never implemented in FreeBSD.
vlimit.3 referred to <sys/vlimit.h> which was removed recently.
vtimes.3 referred to <sys/vtimes.h> which never existed in FreeBSD.

correctly by a cancelled thread.
o Minor spelling (cancelation -> cancellation) and formatting
corrections (missing tab).

This supports cancellation in the linuxthreads port. In the long run,
a much more comprehensive solution will necessitate more dramatic changes
to libc symbol naming, and these aliases will probably need modification
at that time.
MAN8+= rstat_svc.8
The file it talks about doesn't exist on FreeBSD, so there's no point in
installing the manual page. There was already a comment to this effect in
this file, but the entry hadn't been commented out.
rstat.1 and rstat_svc.8 can probably actually be removed.

This feature prevents the update daemon from gratuitously flushing
dirty pages associated with a mapped file-backed region of memory. The
system pager will still page the memory as necessary and the VM system
will still be fully coherent with the filesystem. Modifications made
by other means to the same area of memory, for example by write(), are
unaffected. The feature works on a page-granularity basis.
MAP_NOSYNC allows one to use mmap() to share memory between processes
without incuring any significant filesystem overhead, putting it in
the same performance category as SysV Shared memory and anonymous memory.
