[Glass] Gemstone and Pharo aligment

[Trussardi Dario Romano via Glass]

Ciao,

	I development with Pharo  7.0	and  deployment with Gemstone.

	I have a method is defined both in Pharo and in Gemstone.

	For example 		Collection 	includesAllOf: 	

	Now this method is deprecate in Pharo		to: 		includesAll:

		but Gemstone ( 3.4.2 ) does not define	 includesAll:	 	method.

	How is it best to behave when these problematic are found?

	Thanks,

		Dario
