Boggle kjs-3

This file lives at http://www.pobox.com/~kragen/sw/boggle.html.

I downloaded the latest NetBSD version of Boggle and got it to compile on Linux. It seems to be a little better than the one that came with my Slackware96 system (it uses select() instead of ioctl(x, FIONREAD)) but it didn't compile. Being a lazy SOB, instead of going out and searching the Net for the necessaries to make it compile, I hacked on it until it compiled and ran correctly.

I made the following changes in boggle-kjs-2:

• removed all the calls to the __COPYRIGHT and __RCSID macros, since I don't have 'em (probably should have removed the #ifdefs around them, but I didn't)
• added a comment or two
• fixed a warning (comparing a char to NULL)
• added #include <time.h> where it was needed.
• as shipped, it would wait one millisecond between each time it checked to see if the clock needed to be updated. I changed that to 50 milliseconds because I was spending a lot of time reading strace output.
• added err.h to mkdict.c so it would compile without warnings.
• added `build' and `install' scripts that don't require Berkeley make.

I made the following changes in boggle-kjs-3:

• fixed it so it can handle input dictionaries that have no words beginning with a certain letter,
• simplified the `dictindex' array and mkindex program. (If it matters, it can still use dictindex files from other versions, but its new, simpler dictindex files cannot be used by other versions of boggle.)

I also wrote my own implementation of the err.h functions, figuring it was faster to write my own from the man page than to find the source on the Net.
