comparison libpam-sys/libpam-sys-test/build.rs @ 136:efbc235f01d3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Separate libpam-sys-helpers from libpam-sys. This separates the parts of libpam-sys that don't need linking against libpam from the parts that do need to link against libpam.
