Ok.
I tried as it is now and also with the additional line.
In both cases I created an Eclipse project for cmake and loaded it in Eclipse.
In both cases Eclipse started building the workspace and the indexer was 
running.
In Both cases Eclipse offered autocompletion e.g. for the cmMakefile class, 
also in both cases a block
#ifdef __FLT_MIN__
was highlighted differently than a block
#ifdef __FLT_MIN__X__ 
(which is not a predefined macro).

Which difference should the added line make ?
