Since some time in the last two days, a bootstrap on SCO OSR 5 requires
bison.  Why is that the case?

Because we didn't want to have generated files in the CVS repository.
There's an effort underway to automatically generate those files for
CVS downloads; we'll certainly include the files in releases.

Actually, the only language that requires bison is java (pure parser).

C, C++ and objective C are usually happy with byacc, though gcc things
otherwise, and you will have to convince the Makefile that yacc IS
bison.

(Usually with a x-* fragment that sets BISON=yacc, and with an env
variable that also says YACC=yacc, which takes care of autoconf tests).

Isn't that a bug in the Java frontend then (that should be fixed)?

Someone I highly respect when it comes to portability recently wrote

and I couldn't agree more when it comes to tools like yacc/bison.

No, that one is reasonable. You would have heard from me otherwise :)

No version of yacc that I know of supports pure parsers yet, which is what
java wants, and what bison supports.
