	* gmp-glue.h (cnd_add_n, cnd_sub_n): Moved here, define in terms
	of mpn_cnd_add_n and mpn_sub_n if available, otherwise in terms of
	mpn_addmul_1 and mpn_submul_1. This seems to be an improvement for
	subtraction, but more questionable for addition.

	* ecc-internal.h: Include gmp-glue.h. Deleted corresponding
	include in all files using ecc-internal.h.
	(cnd_add_n, cnd_sub_n): Moved from here.
