That's an old branch sitting on my computer, updating the very old LZMA shipped with crunch with the last one from upstream.
What annoys me is that Crunch is a C++ library but it shipped with the C LZMA library, adding custom wrapping code to make it compilable with a C++ compiler. I don't want to have to replay such change on every LZMA update, so I included it as a C library, meaning I had to make Crunch not only a C++ project but a C++ & C project, meaning selecting a different compiler requires to select both the C++ and C compiler…
An alternative would be to move to the C++ LZMA library but then that requires to port the code to the C++ LZMA API I guess… and I'm lazy. All I want is to make sure we use latest versions of libraries and don't sit on very old dependencies with potential unfixed decades-old issues.
