Too bad then, because...

$ patch -v

Is that new enough, or do we speak about another patch tool? ;-)

Who know, what kind of stupidity I have done here. I couldn't figure
out, what went wrong. :-(

But doesn't matter! I have already got the newest cvs-ball from
anon-CVS. Really nice, that feature :-)))

But with that newest Ruby, there happens some very strange effects
using `irb'. For example...

cle@qiao:~/ruby/ext > irb
irb(main):001:0> f = open("tt.t","r+")
(irb):1: [BUG] Segmentation fault
Aborted

I had core dumps on several occasions, using `irb' with new Ruby :-(

I had also following problem, which I couldn't reduce to some lines of
code...

$ ruby auree.rb test2.auree                      # ok!
$ ruby test2.auree                               # ok!
$ cat test2.auree test1.auree | ruby auree.rb    # ok!
$ cat test2.auree | ruby auree.rb                # BAMPF! CORE DUMP!!!

This happens along a line:

	obj = Classless__.clone

whereby Classless__ is a module.

I do not attach the code yet, as I will complete the doc first.
Furthermore the problem seems to be not so important, as the other three
ways work :-)
