+ 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). */
