Drive letters (i.e. "c:") and backslashes in particular will cause it to 
throw an exception if you don't use the 'native' flag.

I used this simple test program:

     path p1("/this/is/a/test");
     cout << p1.string() << endl;

     path p2("\\this\\is\\a\\test", native);
     cout << p2.string() << endl;

Notice that the native flag is required for the second path. The separators 
are translated to forward slashes internally by the library  so the output 
of the above two paths is the same.

I believe that it uses forward slashes internally and converts to native 
format when asked (at least on Win32).

I also understand (but could be mistaken) that the next version (with I18N 
support) does away with the native checks.
