Can you expand a bit here.  When exactly do the () become (void)? 
Looking at the changes to stabs, mdebug and hpread it appears to reverse 
the default for all non dwarf* cases - assume prototyped rather than 
un-prototyped?  That's a pretty radical change and needs to be clearly 
spelt out in at least the NEWS file.

(Like many people I'm back from a break and am only just getting to 
these e-mails.  This is probably why there were few responses earlier.)
