Modified files:
        include        : string.h 

Log message:
        Make _FFS() macro usable in CPP conditional expressions.  Seems,
        the CPP parser is wrong with a few of '?:' operations.  (The CC
        parser is correct.)
        * include/string.h: Rewrite _FFS() to workaround the difference
        between CPP and CC parsers.  Add a note about the 16 bits width
        of this macro.
