You have earned a beer!!! That's the first report I remember on that
BSP in years!!!  

Does ticker work?  That's usually the next step.

Are you modifying the hello world in c/src/tests/samples or the
standalone example application version?  
 
Either way you can do a make clean in that particular directory.
I know this is what I do so unless Ralf enlightens us both, that
is all I know to offer.

Ralf can probably explain it for sure.  But I am only positive that
--enable-maintainer-mode verifies configure* and Makefile* dependencies
(those based upon auto* tools).

Ralf is there currently any source level dependency checking that 
can be enabled?
