Just specify -I options to gccxml to specify the include path as you would
for any compiler.  Due to unfortunate implementation details, GCC-XML does
not support looking in the same directory as a file to get its headers, so
you might have to specify something like "-I." when running GCC-XML.

Those are the typeinfo node and vtable variables created by GCC internally
for your class "A".  It is safe to ignore them.
