C++ names in backtrace

[Bobo]

Hello all,

I've got a question about gdb & its backtrace command.
When i have a breakpoint hit in gdb in my C++ application i want to see the 
call stack. Using backtrace command i get something like that:
(gdb) backtrace
#0  _ZN7WSLCLAG21select_actuator_parmsEi (this=0x1bc148, parms_set_id=0) at 
WSLCLAG.cpp:151

The C++ names (classes & methods) are not really readable in this output 
(well i can derive them from the characters shown in gdb, but it takes me 
some mental effort and it's also error prone). I understand that the names i 
see are C++ mangled names.
However if i type in gdb l MyClass::my_function i get the correct names 
displayed. Also if i put a breakpoint in this function it gets hit. So gdb 
has some way to translate "human readable" C++ names into mangled onces.

My question:
- is there any way to let gdb display the real C++ names iso the mangled 
ones in commands like backtrace?

I'm using gdb >6.7.1 on SUN Solaris, i build my applications with gcc 3.x.
