What would be "the proper namespaces" for FPC - the namespaces chosen by
Embarcadero (which may change from one Delphi version to another - not
sure whether it happens in reality, of course, but the point is that it
would happen completely outside our control) without any consideration of
our own structure (e.g. rtl versus packages)? Or a different structure for
FPC (e.g. fpc.rtl...., etc.)? Are there any implications for our own units
(the argument about possible conflicts applies to them too)?
