Kevin,
I assume you are referring to an old 2 wire system with a GFCI replacing a two wire outlet! If so, as long as it is marked with the label as you stated it is O.K.

Yes it is code compliant to replace an old 2 wire receptacle with a new 3 wire GFCI.
That said it is a code violation to plug most items (items with s wire plugs) into that ungrounded outlet.
Quote:
250.114 Equipment Connected by Cord and Plug.
Under any of the conditions described in (1) through (4), exposed non?current-carrying metal parts of cord-and-plug-connected equipment likely to become energized shall be grounded.
Exception: Listed tools, listed appliances, and listed equipment covered in (2) through (4) shall not be required to be grounded where protected by a system of double insulation or its equivalent. Double insulated equipment shall be distinctively marked.
(3)In residential occupancies:
a.Refrigerators, freezers, and air conditioners
b.Clothes-washing, clothes-drying, dish-washing machines; kitchen waste disposers; information technology equipment; sump pumps and electrical aquarium equipment
d.Motor-operated appliances of the following types: hedge clippers, lawn mowers, snow blowers, and wet scrubbers
e.Portable handlamps
So if you see an ungrounded GFCI receptacle powering anything in the above list you should bring it up as a violation.
By the way "information technology equipment" is UL speak for computers and almost any other office equipment from phone answering machines to electric pencil sharpeners.
