comparison libpam-sys/src/constants.rs @ 134:6c1e1bdb4164

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use standard #[cfg] directives rather than custom proc macros. Instead of having to do a bunch of custom parsing and other logic that tools often choke on, this change introduces an easy way to depend upon custom #[cfg]s provided by the libpam-sys crate.
