It would probably be best to get the command line expansions to place 
<cxxflags>, <cflags>, etc. at the end of the command line to support this 
usage and other situations where the user wants flags passed directly to the 
compiler to override those set by BBv2.

BBv2 defaults to <warnings>all. After consideration (and the fact that CW 
generates a gazillion warnings in this case) it would be best to set the 
default to <warnings>on.
