This is probably happening because I changed from generating defaults.h 
to generating default-defs.in.h.  Maybe you are getting an old 
defaults.h from your build tree that doesn't include default-defs.h? 
Try removing defaults.h from your build tree and I think this problem 
should be fixed.

For a short time, there was also a generated defaults.cc file, so if you 
have that in your build tree, remove it as  well.
