[exim] Building exim 4.97 without File::FcntlLock

Hi all

When trying to build exim 4.97, it fails because the perl modules
File::FcntlLock is missing. That is quite unfortunate, as it introduces
a new dependency.

I got around it by patching exim_id_update.src, commenting out

use File::FcntlLock;

and twice

$fs->l_whence( SEEK_CUR );


After that, exim builds fine, however I'm not sure if this totally
breaks something.

Can somebody tell me if this is ok, or leaves me with a bad exim?


Below is the patch.

Bye
Tim
