Absolutely no problem doing that.  The new code is a complete
replacement and runs on all the existing platforms.  Perhaps some kind
soul can try on MacOSX?

OK, wiil do.

No, a bit ambitious.  I just cloned that bit from the current cddecoder.
Will fix.

Hmm, that's going to be a problem to maintain compatibility with the
existing cddecooder.h where there's no m_ prefixes.  I just chose to
maintain the status quo.

As for cddb.h, the structs Match, Matches, Track & Album are simple POD
types, albeit with the simplest of constructors, and are intended to be
used like C structs.  Hence the absence of the 'm_' wart.

I have no axe to grind here, but prefixing class member data with this->
causes no overhead and makes the intention clearer.  I have no
reservation adding a 'hungarian' prefix and often use this in more
complex classes.
