Well OK, it ain't too pretty, but it's not too bad either. You can stick
<cxxflags>whatever in your BUILD variable and whatever will go into the C++
command-line ahead of the <sysinclude> directories.

There might be a little bit of compiler-specific knowledge needed about how
the command-line works if you need different options to add to the
#include<> and #include "" paths....
