for the sorts of errors we run into[1]. This also gives us room to put in a
vaguely appropriate casts to silence warnings since our compiler doesn't like
when we compare ssize_t to size_t[2]. Add a cast in sblock.c[3] to silence
a warning because of signed vs. size_t hell (again). Clean up nearby
excessive parenthemutilation[4].

An aside about [4], bde notes that we do not check for a negative value for
the fs bsize. I'm nto going to do that in every situation we use it, one must
expect a reasonable program to pass down reasonable values. Some foot shooting
protection I will tolerate, some I will not. Also he suggests some possible
conditional improvements there, which I may take to heart.
PS: For me at least, this is now WARNS=5 clean...
seed->first value correlation. It breaks rand_r()... Other possible methods
like shuffling inside aray will breaks rand_r() too, because it assumes
only one word state, i.e. nothing extra can be added after seed assignment
in srand().
BTW, for old formulae seed->first value correlation is not so monotonically
increased as with other Linear Congruential Generators of this type only
becase arithmetic overflow happens. But overflow affects distribution
and lower bits very badly, as many articles says, such type of overflow
not improves PRNG.
So, monotonically increased seed->first value correlation problem remains...
Only warnings that could be fixed without changing the generated object
code and without restructuring the source code have been handled.

rewrite to address anyway.
This implementation currently starts a separate agent for each session
instead of connecting each new session to the agent started by the first
one. While this would be a Good Thing (and the old pam_ssh(8) tried to
do it), it's hard to get right. I'll revisit this issue when I've had a
chance to test some modifications to ssh-agent(1).
o Add a MD header private to libc called _fpmath.h; this header
contains bitfield layouts of MD floating-point types.
o Add a MI header private to libc called fpmath.h; this header
contains bitfield layouts of MI floating-point types.
o Add private libc variables to lib/libc/$arch/gen/infinity.c for
storing NaN values.
o Add __double_t and __float_t to <machine/_types.h>, and provide
double_t and float_t typedefs in <math.h>.
o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF,
HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to
<math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via
<machine/float.h>.
o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based
on the size of its argument. __fpclassifyl() is never called on
alpha because (sizeof(long double) == sizeof(double)), which is good
since __fpclassifyl() can't deal with such a small `long double'.
