                        // * Itanium spec says that Float80 encodes to "e" (like LongDouble), but the distinct lengths cause resolution problems.
                        // * Float128 is supposed to encode to "g", but I wanted it to mangle equal to LongDouble.
                        // * Mangling for non-standard complex types is by best guess
                        // * _FloatN is supposed to encode as "DF"N"_"; modified for same reason as above.
