Is there any in-build support for displaying the content of C++ STL unicode 
text-strings in gdb?

In my C++ program I have a lot of std::wstring objects, and I want a 
convenient way to display the content of these unicode strings from gdb 
whenever I break my program. Currently, I just dump the content of the 
memory area manually with "x/20c str_obj._M_dataplus._M_p" (for a 
"std::wstring str_obj" object), but this is inconvenient due to the 
"_M_dataplus._M_p" subfields and results in a very verbose listing. You also 
need to know the string length in advance with this approach.

On my machine I run Fedora linux 9, with gcc/g++ 4.3.0 and gdb 6.8.

Thanks in advance
