There is no need to do that. Any platform that supports the Common
Vendor ABI allows this via ::abi::__cxa_demangle. On gcc versions
earlier than 3.x there used to be a function 'cplus_demangle'. I don't
know whether that was supported on all OS's though.

A long time ago, when this ML was still hosted on Yahoo, I uploaded
example code for Solaris & Linux to do stack back traces (in mangled
form). Steve Shammah also uploaded a version for Win32.

On a side-note, but related if you need to obtain a stack trace at the
point of an exception, the CVABI also allow getting hold of the current
exception type within a catch(...) block using
::abi::__cxa_current_exception_type.
