	* assuan.h (assuan_process_done, assuan_inquire_ext): New
	prototypes.
	* assuan-defs.h (struct assuan_context_s): New members
	in_process_next, in_command, inquire_cb, inquire_cb_data,
	inquire_r_buffer, inquire_r_buffer_len, inquire_membuf.
	(_assuan_inquire_ext_cb, _assuan_inquire_release): New prototypes.

	(std_handler_option, std_handler_bye, std_handler_auth)
	(std_handler_reset, std_handler_end): Use PROCESS_DONE to
	optionally call assuan_process_done if CTX->in_process_next is
	true.
	(assuan_process_done, process_next): New functions.
	(assuan_process_next): Rewritten to support external event
	handling.
	* mkerrors: Do not clear high bits of -1 for old style EOF.
	* assuan-inquire.c (_assuan_inquire_release)
	(_assuan_inquire_ext_cb, assuan_inquire_ext): New functions.
	* assuan-pipe-server.c (_assuan_release_context): Call
	_assuan_inquire_release.

	* assuan-defs.h (struct assuan_context_s): Have full peercred
	structure for HAVE_SO_PEERCRED.
	* assuan-connect.c (assuan_get_peercred) [!HAVE_SO_PEERCRED]: Do
	not try to set PID, UID and GID.

	Change _WIN32 to HAVE_W32_SYSTEM for consistency.

	* assuan-defs.h (struct assuan_context_s): Have full peercred
	structure even if not HAVE_SO_PEERCRED, but not if
	HAVE_W32_SYSTEM.

	* autogen.sh: Require bash.

	* assuan.texi: Clean up typos.

	* assuan-handler.c (assuan_command_parse_fd): Also allow white
	space after FD.

	* assuan-uds.c (uds_reader): Return 0 if recvmsg returns 0.

	* assuan-client.c (assuan_transact): Also translate some of the
	legacy error codes.

Fix memory leak.
Add convenience option for cross build to amd64

Also enhanced libassuan-config and libassuan.m4.
Not really tested!

(At least with the forthcoming gnupg 1.9.91)

	* assuan-client.c (assuan_transact): Do not convert error on
	status line, it is already a gpg-error.  Do convert
	ASSUAN_Server_Fault.

	* assuan.h (assuan_init_socket_server_ext)
	[_ASSUAN_EXT_SYM_PREFIX]: Fix typo in macro.

platforms.

	* tests/fdpassing.c (MOTD): New macro.
	* tests/Makefile.am (AM_CPPFLAGS): New variable.
	* tests/motd: New file.

	* assuan-pipe-connect.c: Add hacks for Slowaris.
	* assuan-socket.c: Likewise here.

	* assuan.h (enum): Avoid trailing comma in enumerator list.  Ugh.

	* mkerrors (_assuan_error): Change return type to assuan_error_t.
	* assuan-buffer.c (_assuan_read_line): Change return type to
	assuan_error_t.  Map returned value of -1.
	(_assuan_write_line): Change type of RC to assuan_error_t.
	* assuan-defs.h (_assuan_read_line, _assuan_error): Likewise for
	prototypes.
