Correct, and there is some danger of a compiler not liking `const'. Indeed, we tend to avoid `const' as it has been responsible for far more than its share of compiler-related bugs. (gcc 3.3 objected to one use of const that Solaris cc accepted today.) There were two more non-static declarations of such tables, in package eda and in src/main/registration.c. -- Brian D.
