We've already got it in libc, but both libraries are incompatible
wrt. their header files and internal data structures. This
incompatibility caused the expr(1) on the fixit floppy to mysteriously
dump core for the colon operator.
Strong 2.2 candidate, since it fixes the usage of MAKEDEV on the fixit
floppy. I'd like to get it reviewed by somebody else though.

This closes PR#1975 and was on my TODO list, so I'm breaking my own "no more
commits before I fly!" rule and taking care of this, since it was at the
very top and Peter shamed me in to taking care of it. This is definitely
a 2.2 candidate.

an archive, the name of the link is truncated to 99 characters, and when
extracting such an archive, an error is reported because it is trying to
create a hard link to a file which doesn't exist. This patch fixes that
problem and has also been sent to the GNU maintainers.

that is stored in the hints file. If that search path contained
a non-existent directory (one, say, that had been removed), and
"ldconfig -m /a/perfectly/good/directory" was run, ldconfig returned
an error status without printing an error message. This caused
some confusing bombs when installing ports, in particular.
I changed it so that non-existent directories from the stored search
path are silently ignored. Only non-existent directories named
explicitly on the command line are treated as errors. Also, a
diagnostic is printed if and only if an error status is returned.
In an unrelated fix, ldconfig now silently ignores any directories
named on the command line when the "-r" option is given. Formerly,
these directories incorrectly made their way into the "search
directories" line of the listing. It really should be an error to
specify directories together with "-r", but I don't have time to
fix the manual page in that way right now.

Remove various bogus pathnames to look up rsh(1) at. Our rsh is in

Also, if it hasn't been found there, use execlp() to look it up. the
latter is required for `weird' environments like a fixit floppy where
the regular /usr/bin hiearrchy is not avaiable. tar should probably
do it similar to dump/restore, and use rcmd(3) instead of forking an

the printing of error messages even for old executables, whose version
of crt0.o is not able to print them.
This fix closes PR bin/1869.
The code in crt0.o for printing error messages from the dynamic linker
is no longer used, because of this change. But it must remain, for
backward compatibility with older dynamic linkers.

libg++'s exception code causes gcc to generate (ahem!) non-conventional
assembler code in -fpic mode that gas and ld choke on. Basically, gas
and ld require than symbols referenced in the GOT (global offset table)
are actually global (as the name implies). It attempted to work around
it before, but didn't quite go far enough to prevent a core dump in ld.
This hack causes GOT referenced symbols to be forced global. This
probably breaks the __EXCEPTION_TABLE__ stuff in pic mode, but heck, it
wasn't even possible to compile with a shared library before at all.
I'm not 100% sure what the bug is. There's two possibilities:
1: gcc/cp/exception.c has to be fixed to stop doing GOT references to
local symbols, or
2: as/ld/symorder/ld.so etc need to be taught about how to keep local
symbols around so that they can be dealt with in GOT references.
John Polstra's elfkit stuff seems to deal with this fine though, which is
why I think it's a "missing feature" in our hacked gas and ld..

Also:

The library search sequence is a little more complete now. Before,
it'd search $LD_LIBRARY_PATH (by opendir/readdir/closedir), then read
the hints file, then read /usr/lib (again by scanning thr directory). It
would then fail if there was no "found" library.
Now, it does LD_LIBRARY_PATH and the hints file the same, but then uses
a longer fallback path. The -R path is fetched from the executable if
specified at build time, the ldconfig path is appended, and /usr/lib is
appended to that. Duplicates are suppressed. This means that simply
placing a new library in /usr/local/lib will work (the same as it did in
/usr/lib) without needing ldconfig -m. It will find it quicker if the
ldconfig is run though.
Similar changes have been made to the NetBSD ld.so, but ours is rather
different now due to John Polstra's speedups and fixes from a while back.
The ldd printf-like format support came direct from NetBSD.

Consider the following code:
case 'O':
output_filename = malloc(strlen(arg)+4);
strcpy(output_filename, arg);
strcat(output_filename, ".tmp");
real_output_filename = arg;
return;
The idea here is to malloc() a buffer big enough to hold the name of
a supplied file name, plus ".tmp". So we malloc() 'size of filename'
bytes plus 4, right? Wrong! ".tmp" is _FIVE_ bytes long! There's a
traling '\0' which strcat() gleefully tacks on _outside_ the bounds
of the buffer. Result: program corrupts own memory. Program SEGVs at
seemingly random times. Bill not like random SEGVs. Bill smash.
Know how I found this? I've been trying to bootstrap -current on my
2.1.0-RELEASE machine at work and I couldn't seem to get libc.a built
because the linker would intermittently blow chunks while executing
things like 'ld -O foo.o -X -r foo.o'. Since this is an initial
bootstrap version of ld, it was linked against the 2.1.0 libc, who's
malloc() behaves differently than that in -current.
Presumeably ld -O doesn't blow up in -current, otherwise someone would
have spotted this already. I don't know if this is a bug or a feature.
Anyway. I'm changing the strlen(arg)+4 to strlen(arg)+5. Bah.
-O filename
Specifies the name of the output file. The file is created as
filename.tmp and when output is complete renamed to filename.
This allows us to:
