[fpc-devel] Generic List in Advanded record does not compile with -MobjFPC, works with -MDelphi (perhaps related to Generics.Collections that I am using)

syntax is not availabe in delphi mode (identifier not found "specialize")
and the generics library where TComparer comes from explicitly sets delphi

In mode ObjFPC you must use "specialize" when you want to specialize a
class, this includes the declaration of the class parent.
Also mixing generics from different modes makes no difference, the compiler
supports that.
