+/* In order to allow a single demangler executable to demangle strings

+   is in that string.  CPLUS_MARKER is usually '$' on systems where the
+   assembler can deal with that.  Where the assembler can't, it's usually
+   '.' (but on many systems '.' is used for other things).  We put the
+   current defined CPLUS_MARKER first (which defaults to '$'), followed
+   by the next most common value, followed by an explicit '$' in case
+   the value of CPLUS_MARKER is not '$'.
+
+   We could avoid this if we could just get g++ to tell us what the actual

+   ensuring that it is the character that terminates the gcc<n>_compiled
