[GCC-XML]Producing "_0" ids when parsing <string>

[Pere Mato Vila]

Dear gccxml,

  First at all, gccxml is excellent an tool. We are very pleased with it
and has allowed us very easily to generate C++ dictionaries for our
object persistency system. 

  We have a problem when parsing std::basic_string<> class. The latest
version 0.4.2 generates much more elements with id's "_0", which are not
resolved. For example, the return type of basic_string::substr() is not
set correctly to what it is in the header file, which is basic_string.
Is there an explanation for these "_0"? Is any any to avoid them?
To reproduce easily the problem I just parsed <string> with the
following commands. 

  Thanks in advance,

				Pere Mato
