I am sure they are. But given we currently only use gcc, we should at least get it working there :-)Also, as a general point, the SConscript files which build things should all be changed to add the local include and lib paths to the front so that local headers mask globally installed headers.I'm 95% sure the include path search order is compiler-dependent, so this probably would only have the desired effect for gcc, but I agree that it's a good statement of intent if nothing else.
