Subject: Re-enable the warning for unused parameters.
X-Git-Tag: 0.1~706
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=884ac59256d19db5ee25d976a4f5e60cce51d7d5

Re-enable the warning for unused parameters.

It's easy enough to squelch the warning with an __attribute__ ((unused))
and it might just catch something for us in the future.
