Re: [CEDET-devel] ede-linux doesn't work with master emacs repo

That looks like a problem with the C/C++ parser.  It knows that t is a 
struct, but claims it is a prototype.  I think you are missing a change 
from a short series of checkins ending on 2010-03-14 that deal with the 
way compound tags (where you have a named struct, AND a declaration of a 
variable t) are dealt with.

I'll take a wild guess that semantic-c.el was not imported right.
