You should also add:

/* The type of the result of a floating point comparison.  This must
  match `__libgcc_cmp_return__' in GCC for the target.  */
typedef int __gcc_CMPtype __attribute__ ((mode (__libgcc_cmp_return__)));
#define CMPtype __gcc_CMPtype

in case CMPtype is different from int. Note, that only typedef is not enough, you also need a #define.

Uros.
