	* nettle-internal.c (nettle_salsa20r12): Cipher struct for
	benchmarking only.
	* nettle-internal.h (nettle_salsa20): Declare it.

1571 1572
	* Makefile.in (eccdata): Depend on mini-gmp files. Drop -lgmp.

1573 1574 1575 1576 1577 1578 1579
	* eccdata.c: Use mini-gmp, to avoid gmp dependency and associated
	configure tests for the *build* system. Replaced mpz_submul_ui by
	mpz_mul_ui + mpz_sub, and gmp_printf and gmp_fprintf by calls to
	mpz_out_str.

	* mini-gmp.h, mini-gmp.c: New files, copied from gmp-5.1.1.

	big-endian systems.

1585 1586 1587 1588
	* Makefile.in (TARGETS): Deleted eccdata, it should be build only

	(clean-here): Exlicitly list it here.

1589 1590 1591 1592
	* asm.m4 (m4_log2): New macro, similar to the one in gmp.

	* umac.h (umac32_ctx, umac64_ctx, umac96_ctx, umac128_ctx): Make
	block count an uint64_t. Reorder some elements to put short values
	together.
	* umac-l2.c (_umac_l2, _umac_l2_final): Make count argument an uint64_t.

	(_umac_l2): Deleted redundant memcpy.
	(_umac_l2, _umac_l2_final): Store input buffer at end of the
