But you can't override the bison_str in the wscript, can you? Without
that, waf doesn't find the files.
(After an svn up for waf):
OK, the bison_str now includes -o, so overriding the variables in the
wscript should be enough.

Complete recompile including the dependency checking (contrary to the
last time - so dependency checking got about twice as fast on my machine
since 0.9.1). The current SVN does it not at the beginning but
interspersed with compilation, so I missed that.

Very useful for an SMP machine - without that, the complete build takes
2:00 minutes instead of 1:07 here.
I think I got something here... hangs at aiexperience.c again (-j2 this
time), with no other error message, the traceback occurred a few files
before aiexperience.c (which, incidentally, is the last file to be
compiled), I guess with -j3 it was even farther up so I didn't see it:

Hm, OK... but it's a bit counterintuitive having the single waf script
which effectively is not used if there's an older version in
~/.waf-x.y.z... Imagine we strip waf of some unneeded stuff like OCAML,
and someone uses the same waf version in another project and needs it.
Then waf will break in a totally opaque way.

Hmm... the big difference I see here is: The waf variants have to be
defined in the wscript, while the autostuff can have any number of
different configurations just by running ./configure in a different
directory. I really came to like that feature of autoconf, that's the
only thing I really miss in waf right now.
