5d9fefacf2 Use #include "fenv.h" instead of #include <fenv.h>. This makes it 
more convenient to compile the math library by itself.

8d105928ec In r225809 the intention was to send VEOF only once if STDIN was not a 
terminal. Unfortunately the fix was incorrect and for flushtime > 0 it
keept sending VEOF.

Sent VEOF generates ^D\b\b echoed by the terminal, which was reported
in bin/161526. Note, we still send VEOF at least once. Otherwise
commands like below would hang forever:

  echo 1 |script /tmp/script.out cat

53883e0c24 Add support for IPv4 /31 prefixes, as described in RFC3021. 
To run a /31 network, participating hosts MUST drop support
for directed broadcasts, and treat the first and last addresses
on subnet as unicast. The broadcast address for the prefix
should be the link local broadcast address, INADDR_BROADCAST.

b365d954cc Remove last remnants of classful addressing: 
- Remove ia_net, ia_netmask, ia_netbroadcast from struct in_ifaddr.
- Remove net.inet.ip.subnetsarelocal, I bet no one need it in 2011.
- fix bug when we were not forwarding to a host which matches classful
  net address. For example router having 192.168.x.y/16 network attached,
  would not forward traffic to 192.168.*.0, which are legal IPs in
  CIDR world.
- For compatibility, leave autoguessing of mask based on class.

b052ec9065 Various changes to improve the accuracy and speed of log{2,10}{,f}. 
- Rename __kernel_log() to k_log1p().
- Move some of the work that was previously done in the kernel log into
  the callers.  This enables further refactoring to improve accuracy or
  speed, although I don't recall the details.
- Use extra precision when adding the final scaling term, which improves
  accuracy.
- Describe and work around compiler problems that break some of the
  multiprecision calculations.

A fix for a small bug is also included:
- Add a special case for log*(1).  This is needed to ensure that log*(1) == +0
  instead of -0, even when the rounding mode is FE_DOWNWARD.

15d5d9deb1 Don't define FP_FAST_FMA on sparc64; with the recent fixes, fma() is 
no longer "fast" on sparc64.  (It really wasn't to begin with, since
the old implementation was using long doubles, and long doubles are
emulated in software on sparc64.)

ec95083025 Fix a double-rounding bug in fma{,f,l}. The bug would occur in 
round-to-nearest mode when the result, rounded to twice machine
precision, was exactly halfway between two machine-precision
values.  The essence of the fix is to simulate a "sticky bit" in
the pathological cases, which is how hardware implementations
break the ties.
