This would be quite a big problem if widespread, which probably makes it 
something specific to your situation.

Run "ecosconfig export foo.ecm" in the same directory as your .ecc to 
generate a foo.ecm file that will show you what options are different from 
the default (although a few of them e.g. for header files get set 
automatically in the net template).
