+   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

+   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

+
+SYNOPSIS
+
+	static int
+	demangle_signature (struct work_stuff *work, const char **mangled,
+			    string *declp);
+
+DESCRIPTION
+
+	Consume and demangle the signature portion of the mangled name.
+
+	DECLP is the string where demangled output is being built.  At
+	entry it contains the demangled root name from the mangled name
+	prefix.  I.E. either a demangled operator name or the root function
+	name.  In some special cases, it may contain nothing.
+
+	*MANGLED points to the current unconsumed location in the mangled
+	name.  As tokens are consumed and demangling is performed, the
+	pointer is updated to continuously point at the next token to
+	be consumed.
+
+	Demangling GNU style mangled names is nasty because there is no
+	explicit token that marks the start of the outermost function
+	argument list.

+
+	MANGLED points to the current pointer into the mangled name.  As each

+	the current mangled name pointer points to the first character of
+	the mangled name.  Upon exit, it should point to the first character
+	of the signature if demangling was successful, or to the first
+	unconsumed character if demangling of the prefix was unsuccessful.

+
+   g++ produces the names:

+     foo__FiR3fooiT1iT1
+
+   while lcc (and presumably other ARM style compilers as well) produces:
+
+     foo__FiR3fooT1T2T1T2
+     __ct__3fooFiR3fooT1T2T1T2
+
+   Note that g++ bases it's type numbers starting at zero and counts all
+   previously seen types, while lucid/ARM bases it's type numbers starting
+   at one and only considers types after it has seen the 'F' character
+   indicating the start of the function args.  For lucid/ARM style, we
+   account for this difference by discarding any previously seen types when
+   we see the 'F' character, and subtracting one from the type number
+   reference.
