/* Tuning code does two things. It uses the gf2x library, compiled with
 * its default settings, and it tries as well other candidate functions,
 * to see if performance improves. The trick is that the code for these
 * functions is also valid code for the library include files. Therefore,
 * the ``candidate functions'' must not have the same name as in the gf2x
 * library, because otherwise we could end up with two different
 * definitions for the same code, and ambiguity as to what gf2x_mul_X
 * stands for: the library code, or the function we are currently testing ?
 */

/* First we include the gf2x standard inlines. Not necessarily because we
 * need them, but rather because we might have seen a prototype for one
 * of these with static declaration. Therefore we need the code.
 * Including it here causes declaration for the standard functions to be
 * emitted, since this header is protected: when gf2x-small.h includes
 * gf2x/gf2x_mul@@SIZE@@.h, the file _is_ read due to the fact that we
 * undefine the protection flag below. However this file
 * tuning_undefs_@@SIZE@@.h  is not included again.
