2000-02-17  bertrand  <Bertrand.Guiheneuf@aful.org>

	* camel/camel-formatter.c (handle_text_plain):
	(handle_text_html): use camel_stream_reset instead
	of seek. The formatter should be able to work
	with all streams, not only seekable streams.
	In the case where some provider implementation
	would not be able to provide a reset method
	to their stream, implementors would have
	to find a workaround.

	* camel/camel-session.c (camel_session_new): use
	(void) instean of () in function decl.

	* camel/camel-folder.c: ifdef async operation
	related code.

	* camel/camel-seekable-stream.c (_seek): added a warning.
	(_reset): default implementation of reset for seekable
	stream.

	* camel/camel-mime-message.h: set_received_date declaration fix.
	cosmetic changes.

	* camel/providers/mbox/camel-mbox-provider.c (camel_provider_module_init):
	use (void) instead of ().

	* camel/camel-stream.c (camel_stream_reset):
	new method for CamelStream.
