That's no longer true I think - as of v17 the source tarballs won't
contain any generated files, so you do need flex and bison if you want
to do any sort of development. I am mildly astonished to hear that
too-old versions of those tools aren't extinct in the wild, though.
In any case I agree with the recommendation to install and use git
rather than downloading source tarballs.
