You need to reread the GPL to understand it correctly:
The GPL requires to publish "all" from "the work" to be published under the
GPL but not more.
- The build scripts in many cases are not part of "the work".
This is true for all software that e.g. uses autoconf.
This is true for all software that usees other independent
build software.
This is true in the cdrtools case.
Your misunderstanding is that you did not grok the fact that the GPL
distinguishes between "the work" and "the whole source".
- "the work" needs to be under GPL
- The GPL does not require _anyting_ for the other parts that are
needed to create "the whole source" except that it needs to be
published.
Other code that is not derived from the GPL code is not part of "the work":
- You do not need to put "non-derived" code under the GPL.
[ the rest of your claims is just a flollow up mistake ]
