Alexandre Julliard a69b88b2f2 Release 980315 
Sun Mar 15 03:46:50 1998  Dimitrie O. Paun  <dimi@mail.cs.toronto.edu>

	* [*/*]
	Fixed some dprintf_ such that there is one and only one
	new line for each dprintf and that new line occurs at the end.
	Transformed some fprintfs into proper debug statements.
	Removed much redundancy from most of the debug statements. The
	redundancy appeared because now the component and function
	name is output automatically. Most debug statements also used to
	output the name of the function.
	All these changes prepared the source to switch completely to
	the new debugging interface.
	For more info, refer to ./documentation/debug-msg
