Hi, the game Battle of Wesnoth contained in Debian is licensed under GPL v2+. Now a dependence on the Boost libraries (www.boost.org) was added and the configure script missed a test for it. So I integrated (see https://gna.org/bugs/?10419) the file boost.m4 from http://repo.or.cz/w/boost.m4.git which is licensed under GPL v3+ into the build system (I these macros from configure.ac).
Now the question: Could the different license versions cause problems? Can Wesnoth still be shipped as GPL v2+ or not? I would also like to know the following (as the author is willing to relicense boost.m4 if necessary to the Boost license): If a possible non-free software which uses Boost would start using boost.m4 in their build environment, is it necessary to relicense the whole software under GPL v3+? I searched the web for quite some time and couldn't find an explicit answer except: According to GPL v2 the build system belongs to the source code of software but is the integration and usage of M4 macros a modified work? Since I mentioned that some autoconf macros contain a GPL exception I have doubts about compatibility and Eric S. Raymond asked me to resolve it so please help ...
