- -elf in CFLAGS had no effect except to reduce portability.
- -elf in LDFLAGS had even less effect, since LDFLAGS is not used.
- -Wall in CFLAGS had no effect except to reduce portability and break
overriding of WARNS, since the setting of WARNS implies -Wall.
an application compiled -static with libthr would dump core in
malloc(3) because the stub thread initialization routine in libc would
be used instead of the libthr supplied one.
don't allow it at the moment, the correct thing to do is try again.
Otherwise, libthr would fail this test because it doesn't allow
an unlimited number of concurrent threads per application.
that the old API (passing "" as the attribute name to the _get_
interface) is now deprecated (and was probably a bad idea).

o Make sure the arguments to ctx_wrapper() are loaded from the
backing store by forcing an underflow. Do this by making all
registers in the register frame local.
is not called, and no static rules match an outgoing packet, the
latter retains its source IP address. This is in support of the
"static NAT only" mode.
o Up to 8 arguments are allowed. This is the number of arguments
passed in registers. Subsequent registers are passed on the stack.
Trying to deal with this is not easy in C and likely forces us to
use assembly code. Let's avoid that for now. There's no indication
that more than 8 arguments is a strong requirement (Linux also has
an 8 argument limit).
o We expect that the stack base is 16-byte aligned and the stack
size is a multiple of 16-byte. We bomb out if this is not the case.
We probably want to be less strict by enforcing it ourselves. For
now it's better to not hide gross alignment bogons by silently
correcting it.
an excessive close() on one of these descriptors would cause
a memory for this descriptor to be allocated in the internal
descriptor table. When this descriptor gets used again, e.g.
through the call to open() or socket(), the descriptor would
be erroneously left in the blocking mode, and the whole
application would get stuck on a blocking operation, e.g.,
in accept(2).
Prevent this bug from happening by disallowing close() against
non-active descriptors (return -1 and set errno to EBADF in
this case).

to a buffer in the big key/data case, memmove() was used on pointers
to size_ts, but only sizeof(u_int32_t) bytes where copied. This broke
on big_endian architectures where sizeof(size_t) > sizeof(u_int32_t).
This bug broke portupgrade (by way of ruby_bdb1) on sparc64.
