yet further changes 11/12 by pshields

1) first_one has now been written in ppc assembly, which
reduces the time of the benchmark to about 3.5 seconds with
-O3 optimization on my g3.  This is about .62 x as fast as
Tom Kerrigan's Athlon 2000+, and would correlate with a score
of about 1170 on the posted benchmarks.


more changes 11/6 by pshields

1) first_one and last_one have been moved into board.c to
eliminate warnings.  The C version of first_one has been
recoded in C to reduce the time on the benchmark to about 
12-13 seconds (with optimization -O3) on my g3.  (The book
works if you make sure book.txt is in the same directory as
as the executable.)


new changes 11/1 by pshields

1) The last_one function in protos.h has been converted into
PPC assembly code.  The project can now be compiled with -O3
flag which will allow inlining the function.  It reduces the
time on the benchmark to about 47 seconds on my g3. 


tscp_mac--changes by P. Shields

These files have been modified from the TSCP181_msj version 
(with bitboards by MJ Sherwin) from Tom Kerrigan's site:

1) The 80x86 assembly code in protos.h has been replaced by 
high level C code.  To make it fast again, this C code would 
have to be turned into PPC assembly.

2) The definitions at the bottom of defs.h have been added
to provide a 64 bit type for the bitboards and definitions
of the structs which are needed to get the system time using
gettimeofday() instead of the deprecated (in 10.3) ftime().

3) The function get_ms() in main.c has been rewritten to 
use gettimeofday. The #include has been changed to <time.h>
from <timeb.h>.

This version is _very_ slow, about 77 seconds to complete
the benchmark.
