-/* In order to allow a single demangler executable to demangle strings
- using various common values of CPLUS_MARKER, as well as any specific
- one set at compile time, we maintain a string containing all the
- commonly used ones, and check to see if the marker we are looking for
- 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
- cplus marker character is as part of the debug information, perhaps by
- ensuring that it is the character that terminates the gcc<n>_compiled
- marker symbol (FIXME). */

+ - Occasionally '_' if neither of the above is usable
