This prevents the compiler from generating duplicate debug information for 
enumerators, first for the definition of the enumeration type and then for 
the individual constants themselves.

Tested on i586-suse-linux, applied on the mainline and 4.5 branch.

	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Enumeration_Type>: Do
	not generate debug info for individual enumerators.
