GCC artificial flag is not very consistent, but the test (sourceline != 0) is. 
I don't know if or how gccxml exports the source line of a type declaration 
but I assume it does.

std and __gnu_cxx are the only artificial namespaces GCC creates in any case, 
so you can ignore them by name if you need to.
