Well, I saw that thread when I was looking up for possible solutions, 
but that is not the same problem you had in 
http://www.nabble.com/Re:-Installing-Bison-from-CVS-p10235415.html This 
one is a different one, and I solved it already, the description of the 
solution is in my original email :-D It was really a bug on 
gnulib-tools, I suppose, a mis-escaped backslash.
