If you have a C compiler you can restart at iteration 25. If not you
will have to start from scratch again. Here's how to hack it:

1) Make a copy of tbmake.c (call it tbmake25.c or whatever)

2) Take the copy and locate the "/* announce high water marks */"
comment.

3) Before that comment, set the high water marks accordingly. For KRRKR
that is:

   maxmatev[c_w]=31; maxlosev[c_w]=19; maxmatev[c_b]=20;
maxlosev[c_b]=31;

   (Perhaps I'm wrong here but it looks right.)

4) after the block where the high water marks are announced, find
"distance=1"
   and change that to "distance=25"

5) remove all the code before the line you just entered to set the high
water
   marks up to (& including) the block with the "/* initialize file
contents */"
   comment.

6) recompile and run with the modified sources.

Five days and one hour for 25 iterations seems excessive anyway. I built
the whole KRRKR class in less than 2 days I think.
