	Include cbc.h instead.

	* des-compat.c: Reverted const change, now all the des_key_sched

	* cbc.c (cbc_encrypt, cbc_decrypt_internal, cbc_decrypt): Use it

	compatibility with nettle_crypt_func.

	makes such as tru64's, which tries to understand %-patterns, but
	doesn't get it right.
	(SUFFIXES): Added .html.
	(.texinfo.html): Rewrote rule to use a traditional suffix target.
	
	* configure.ac (enable_assembler): Explicitly set
	enable_assembler=no, on architectures where we have no assembler
	files. 
	(ENABLE_ASSEMBLER, ENABLE_SHARED): New automake conditionals.

	(pgp_put_mpi): Condition on HAVE_LIBGMP.

	* pgp.h: Don't include bignum.h, to make it possible to compile
	the non-bignum parts of pgp-encode.c without bignum support. Needs
	to be fixed properly before the pgp interface is advertised.
