Hmm.  I don't have a CVS binutils tree around, but I get, with GDB
from current CVS:

(gdb) maint demangle _ZN1C6CClassaSERKS0_
Can't demangle "_ZN1C6CClassaSERKS0_"

So either we're using different demanglers or else there's something
strange about maint demangle/class_name_from_physname.  Either of
which is possible - nobody other than me uses class_name_from_physname
regularly, after all, and maint demangle is only a maint command.
