THought I already answered this, but here you go...
Now that I think of it again... check out Codewarrior from metrowerks - is it www.metrowerks.com? I think they were bought by Motorola. Covers C/C++ and Java for linux and other platforms. Pretty good tools a few years ago.
Check out http://www.bullseye.com/ for a product called C-Cover. I can't vouch for it , but it seems to be used mostly for C/C++.
