OK, that's certainly fair. :-)
However, most other packages in Chapter 5 have a little blurb like
this: "Compilation is now complete. As discussed earlier, running the
test suite is not mandatory..." Bison is an outlier (along with
DejaGNU), in that it just says: "To test the results, issue:"
There are a few other packages (expect, ncurses, perl, etc.) in
Chapter 5 that mention specific problems with the test suites, as
well. I think it would be helpful to have a comment like that for
