Problems compiling: givaro, examples

[Laurent Bartholdi]

I just pulled the latest sources from github, and run into a bunch of problems:

-- building givaro. It used to work well (4.0.5), but with the new 4.2.0 I get

-- compiling some examples in linbox:

% (cd tests; make la-block-lanczos)

.... lots of errors...

I'm happy to send the log of compilation, but somehow google groups doesn't let me attach a file.
