Hi,

   I tried you sample code, and it worked fine for me, providing 37 
possible completions.

   Your best bet is to use:

M-x semantic-analyze-debug-assist RET

This command appears to have lost it's autoload cookie in CEDET/BZR, so 
you may need to (require 'semantic/analyze/debug) to get the function.

This will dump out all the possible reasons it can't find vec, and 
perhaps one of them will identify a lost header or something that will 
help you fix things.

Good Luck
Eric
