consistent handling of negative ids on 32bit/64bit systems.
The only negative uid/gid allowed is -1 which is special-cased
so it can be preserved when writing the new master.passwd file
instead of being written as an unsigned number.  OK deraadt@

The issetugid() API is supposed to make a strong promise where "0
means it is safe to look at the environment".  Way back in the past
someone on the OpenSSL team responded to the environment access danger
by creating a wrapper called OPENSSL_issetugid, and went to use it a
number of places.  However, by default on systems lacking true
issetugid(), OPENSSL_issetugid returns 0.  0 indicating safely.  False
safety.  Which means OPENSSL_issetugid() fails to make any sort of
promise about safety, in fact it is just the opposite.
Can you believe the OpenSSL team?
This nastiness was noticed over the years, however noone could gain traction
and get it fixed in OpenSSL.  Also see a paragraph about this in
http://www.tedunangst.com/flak/post/worst-common-denominator-programming

handling from libpthread to libc, though libpthread still overrides the
inner call to handle locking and thread-library reinitialization.

routines on hppa, the cause for sha512-parisc subtly misbehaving has been
found: despite having fallback pa1.1 code when running on a 32-bit cpu, the
shift constants used in the sigma computations in sha512 are >= 32 and are
silently truncated to 5 bits by the assembler, so there is no chance of
getting this code to work on a non-pa2.0 processor.
However, the pa1.1 fallback code for sha256 is safe, as it never attempts to
shift by more than 31, so reenable it again.

that should never have been installed.

What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time.  This makes the
tree safe for /usr/include/tzfile.h removal.  The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree.  Actual removal of tzfile.h is pending
a ports build.  Based on a diff from deraadt@
