[Dovecot] madvise() errors

(I think this has been mentioned before.)

Do these hurt?:

May 2 13:41:30 sysname dovecot: POP3(xxxx): madvise() failed with file /users/xx/xxxx/Maildir/dovecot.index.log: Operation not supported

I think not, since I've been seeing them forever. But they do muddy the logs. This is on an old BSD/OS server, where the man page for madvise ends with:

BUGS This call is not yet supported.

The messages are *only* about index.log files.

Would it be possible to either suppress the log message if the error is specifically "not supported" or, better yet, detect it at configure time?

Completely understandable if it's not worth the effort, though.
