Thank you for your kind help. After some checking, it proved out that
file configure.ac contained CRLF EOL's.

If I do:

   $ git check-attr -a -- configure.ac
   $

I get no output, so configure.ac does not have any "eol" attribute set
to "lf". And the .gitattributes files does not tell anything either.

After doing some dos2unix on configure.ac, the ./autogen.sh runs
normally and I get a configure script --- which I have not yet used.
