Flex is a standard programming tool used in lots of 
programs, don't blame Lilypond for that. Apparently, 
there's some unfortunate incompatibility  between the
Flex version you use and gcc 3.0, but as far as I can 
understand from earlier mails on this list, there is a 
newer version available that solves this problem and
makes it possible to compile both Lilypond and all other
programs that use Flex with gcc 3.0. If you don't have a
Flex version that doesn't work together with your 
compiler, than you don't have a coherent C programming

I recommend that you browse the mailing list archives
of lilypond-user, lilypond-devel and bug-lilypond to
find more details on this specific problem.
Searchable archives (with some delay) can be found
and correspondingly for the other lists.
