Comment (by akim.demaille@…):

 Replying to [comment:25 larryv@…]:
 > Does omitting the `--disable-yacc` configure option change the build
 (other than installing the yacc executable, static library, and man page)?
 Is there a good reason we shouldn’t just do that always and get rid of the
 `yacc` variant?

 {{{
 if ENABLE_YACC
 bin_SCRIPTS = src/yacc
 endif
 EXTRA_SCRIPTS = src/yacc
 MOSTLYCLEANFILES += src/yacc
 }}}

 So if `--disable-yacc` is passed, yacc is not built by default (i.e.,
 `make`) but `make src/yacc` would work.

 I personally don't understand the point of not installing `yacc`.  Bison
 is designed to provide compatibility with yacc (when given `--yacc`), and
 that's precisely the point of `yacc`: to provide the user with a POSIX
 Yacc.  We are talking about a shell-script of a couple of lines, why the
 bother?  Byacc has always been called byacc, not yacc.
