[fpc-pascal] Unexpected warning messages...

[Gene Buckle]

I've started working with FPC again after a VERY long hiatus (like 15+ 
years!) and the application I'm working on uses TObjectCollection from 
the Generics.Collection unit.

When compiling I get the following warnings from generics.dictionaries 
and I was wondering why that is happening - I'd have thought that "base" 
units would always compile cleanly. I know I can filter them out in 
Lazarus, but I would rather not if it can be avoided on the assumption 
that warnings are warnings for a *reason*. :)

Thanks!
