fetchnews.c: invalid operands to binary

[Antoine Jacoutot]

Hi...

I'm trying to compile the 2.2.13 version of cyrus-imapd under OpenBSD.
I've never had issues with earlier versions, but now, there seems to be 
some changes in imap/fetchnews.c and I get the following error:

cc -c -I.. -I./../lib -I/usr/include -I./../sieve -I/usr/local/include/db4 
-I/usr/local/include -I/usr/include -I/usr/include -I/usr/local/include 
-DHAVE_CONFIG_H -O2 -pipe -fPIC  fetchnews.c
fetchnews.c: In function `main':
fetchnews.c:436: error: invalid operands to binary -
*** Error code 1

  If I change le line 
#436 from
stamp -= timezone;
to
stamp = timezone;

then it compiles fine. BUT, I'm not a developper and I have no idea how 
this change is good/dangerous... or not ???
I would appreciate any hints on this.

Thanks!

Regards,
