trifectatechfoundation/bzip2-rs#40 (comment)

bzip2 has added a new feature, to opt in to use libbz2-rs-sys, a pure-rust implementation created by calling c2rust on the original C codebase.

This results in a pure-rust implementation that is:

easier to cross compile
No external c compiler needs to be installed
No build-script or build-script dependencies
pure rust implementation of bzip2 can be LTO against rust code, without having to configure the system to use the same clang version to compile

I believe zstd would also benefit from having a pure-rust implementation gated by a feature?

I have tried this out today and encountered several errors, reported to upstream immunant/c2rust#1193
