Try the minted package. It uses the external Pygments python syntax highlighter and is therefore quite powerful. You need to use the -shell-escape option to allow it to call the required external executables.

And there are GNU Source-highlight:

and hightlight:
http://www.andre-simon.de/

They can export LaTeX code.

PS.
In ConTeXt, there is a t-vim module, which calls VIM to highlighting the program code.
