That's good news. My problem with the old libmcc was that it was released under GPLv2. I could not use it, otherwise I would have to release my project's source code. libmcc should be published under a less restrictive license like LGPLv2.
libmcc2 has 2 license files with it: GPLv2 and BSD. Does this mean it is now dual-licensed? If so, what about the the header comments in libmcc2.c and libmcc2.h? There only GPLv2 is mentioned.
