I personally think a static analysis tooling with even only a single 
false positive caused by inexact invocation of the tooling (i.e., not 
passing the same command line switches as are passed to the real 
compiler) would be just a waste of time (and I personally wouldn't even 
bother looking at the results then).  Your mileage may vary---widely 
even---of course.  And I surely don't want to kill any enthusiasm and 
effort with this, just put it into perspective.

And from the other parts of this thread I see a move to that already 
existing gbuild-to-ide thing, which sounds very promising.
