	* sem_prag.adb (Process_Import_Or_Interface): Exit the homonym
	loop if the pragma does not come from source, so that an implicit
	pragma Import only applies to the first declaration, avoiding
	possible conflicts with earlier explicit and implicit declarations
	due to multiple Provide_Shift_Operators pragmas.
	(Set_Imported): Remove previous fix that bypassed pragma duplication
	error.
	* gnat_rm.texi: Change 'equivalent' to 'similar' in description
	of Provide_Shift_Operators.
