GCC's __attribute__ handling seems to be a little bit stricter with GCC 3.3.3:

   * When a function declaration uses it, the corresponding definition has to
     use it, too.

   * Syntactically it is allowed only at the beginning of the function
     definition.

Let's hope that the current syntax is backwards compatible...
