Why I have 'copies' of exim executable files in '/usr/sbin' directory?

[redesb]

Looking for exim executables, I found that in my '/usr/sbin' directory I have copies of all exim executables with '.O' at the end except thereof exim, see the following partial listing of that directory:

-rwxr-xr-x 1 root root   10910 nov 12 03:14 /usr/sbin/exicyclog

-rwxr-xr-x 1 root root    4302 nov 12 03:14 /usr/sbin/exiwhat.O

Can someone tell me if this is normal or if I have to start worrying?

Looks right to me. I only checked a fw of them; they may all be perl files. I'm not sure why the .0 files are there; you could ask on the exim-users mailing list.
