monit OpenBSD port fixed (Mac OS X process code fix remains)

[Martin Pala]

Hi,

i have fixed OpenBSD port (compile time warnings and process code) - 
changes are in cvs now.

Before monit-4.4 release we should review Mac OS X process code 
('process/sysdep_DARWIN.c') which needs to be fixed as well. I have no 
access to this platform, it will be super when someone can try to fix it 
(FreeBSD and OpenBSD code works good now => it should be possible to 
reuse it).

Thanks ;)
Martin
