+SYNOPSIS
+ char *bfd_demangle (bfd *, const char *, int);
+
+DESCRIPTION
+ Wrapper around cplus_demangle. Strips leading underscores and
+ other such chars that would otherwise confuse the demangler.
+ If passed a g++ v3 ABI mangled name, returns a buffer allocated
+ with malloc holding the demangled name. Returns NULL otherwise
+ and on memory alloc failure.
