* On Solaris cc when compile with -Xc (which results in BASEB=16
because it eliminates the long long type), some of the hash
functions fail.
NOTE: As a work-a-round, Solaris cc users should compile
with -DFORCE_STDC and without -Xc.

###
Rewrote command line / argument processing code. Calc is now
using getopt(3) argument processing.
Fixed a memory leak related to converting strings to numbers
in the str2q() function in qio.c.
Fixed a problem with reading uninitialized memory in the
v_subtype of a VALUE in the copyvalue() function in value.c.
Fixed problems in func.c where temporary VALUEs were not
having their v_type elements initialized.
Fixed a memory leak in qpi() in qtrans.c.
Fixed a memory leak in math_getdivertedio() in zio.c.
Fixed a problem with points going beyond the end of allocated
memory in addstring() in string.c.
Fixed a memory leak in zgcdrem(), f_putenv(), zlog() and
zlog10() in zfunc.c.
Fixed a memory leak in zdiv() and zshift() in zmath.c.
Fixed memory leaks in zsrand() in zrand.c.
Fixed a memory leak in zsrandom1() in zrandom.c.
Added seed() builtin to return a 64 bit seed for a
psuedo-random generator.
Added functionality from Ernest Bowen <ernie@turing.une.edu.au>
to give arguments as well as function names after definitions when
calc_debug >= 0.
Added functionality from Ernest Bowen <ernie@turing.une.edu.au> to
permit nested "= {...}" assignments for lists as well as matrices
and objects. Now one can have a list, matrix or object, some of
whose elements are lists, matrices or objects, to any depth of
recursion, and assign values to any number of particular elements
by an appropriate "initialization" expression. For example:
A = mat[2] = {list(1,2), list(3,4,list(5,6))};
and then assign values to the 6 number elements by:
A = {{7,8}, {9,10,{11,12}}};
Closed files that were previously left open from test4600.cal
as executed by regress.cal and from opening /dev/null by
regress.cal itself.
Fixed memory leaks from f_strprintf() and f_putenv() in func.c.
The regress.cal test suite calls freeredc(), freestatics() and
freeglobals() at the end of the test suite to free storage
consumed during the regression.
Fixed misc compile warnings and notices.

NAME
seed - return a value that may be used to seed a pseudo-random generator
SYNOPSIS
seed()
TYPES
return integer
DESCRIPTION
Generate a pseudo-random seed based on a collection of system and process
information. The seed() builtin function returns a value:
0 <= seed < 2^64
IMPORTANT WARNING:
It should be pointed out that the information collected by seed
is almost certainly non-chaotic. This function is likely not
suitable for applications (such as cryptographic applications)
where the unpredictability of seeds is critical. For such critical
applications, lavarand should be used. Seed:
http://lavarand.sgi.com
for information about seeding a pseudo-random number generator
(such as rand() or random()) with the cryptographic hash of the
digitization of chaotic system.
Given the above warning, this builtin function produces a seed that is
suitable for most applications that desire a different pseudo-random
sequence each time they are run.
The return value of this builtin function should NOT be considered
a random or pseudo-random value. The return value should be used
as an argument to a seed function such as srand() or srandom().
EXAMPLE
> print srand(seed())
RAND state
> print srandom(seed())
