An explanation of what/why can be found starting at GCC's own pages:
http://gcc.gnu.org/contribute.html and the following the "see some docs"
link for more.

I'll send you the forms by private email shortly.

To be a drop-in replacement for the libiberty stuff, you would need to
provide those two functions as wrappers to your own demangler.  That way
existing code won't change.  Take a look at libiberty/cp-demangle.c.

The cplus_demangle_v3 is the more public entry point, I /think/, and
the __cxa_demangle one is for completeness with the rest of the new ABI.
There are a couple of places in libcups++ where it's almost called, but
avoided with a comment saying, "must wait until it's LGPL."
