Hello, Pierre,

Thanks for the advice.
I wrote to the maintainers of the flex project... Here is his reply :

-----------------------------------------------------------------------
"this is a known issue and has already been resolved. Beta releases of
flex already handle the gcc-3.2 issues. You can find beta releases of
flex at:

ftp://ftp.uncg.edu/people/wlestes/
------------------------------------------------------------------------

So, I've tried the two last versions of flex to compile lilypond 
1.6.2... Seems better (or less bad) (as far as I can understand the 
problems :), but does not work !

Here is the log :

Is anybody knowing c++ and flex can give a fix/patch ???
Thanks in advance,
