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). */
