Is it possible to specify separate compile flags for c and c++?  It doesn't look like it.  If not, this would be a nice feature.  Is there a place to post feature requests?  
I would also like to have a bit more control over the actual link command used.  I had to edit the cbp file by hand to jiggle the lib order and lib directory order to get the link to work for a large application.  This is really a problem with gcc that I have to do this at all, but it would be nice if C::B provided finer grain control over the link step.
This is an excellent tool!  I just started using it on Ubuntu yesterday and I have ported my VS projects over without much problems.  Thank you!
