fix: last --jobserver-auth wins by weihanglo · Pull Request #67 · rust-lang/jobserver-rs (original) (raw)

From the GNU make manual1:

Be aware that the MAKEFLAGS variable may contain multiple
instances of the --jobserver-auth= option.
Only the last instance is relevant.

Hence this commit makes it so.

With this commit, --jobserver-auth also takes precedence over
--jobserver-fds, even when --jobserver-fds is the last instance
of these flags. This is made intentionally since --jobserver-fds
was an undocumented internal-only flag before --jobserver-auth
made public, according to this announcement2.

fixes #66
