[Exim] Compling on Digital Unix

Digital Unix (OSF1) version 4.x apparently does not define socklen_t. I
don't know about later versions of Tru64.

Exim won't compile out of the box on Digital Unix. I was able to get it
to compile by adding

#DEFINE socklen_t unsigned int

into OS/os.h-OSF1, but...

I don't know for sure that unsigned int is the correct type on an Alpha,
and this is not a very good permanent fix.

Should I put in a bug report recommending that the correct #DEFINE be
added to os.h-OSF1? (Anyone know what that should be?) If so, how
should I do this?
