Currently the rure crate is only buildable as a cstaticlib or cdylib format (code), and cannot be easily included within a larger rust cstaticlib as a dependency. It would be nice if this crate also allowed itself to be built as a normal rlib dependency, so that it could be depended on in this way. This would make it easier to share a single copy of the regex crate and its dependencies between C/C++ and Rust code within a single project.
