Of course there are. For example unit dialogs. This is solved by the
search path.

There are even conflicting names in the system unit. For example the
system unit has a THandle that is 32bit under linux 64bit, but Lazarus
needs a THandle that is 64bit under 64bit. Gladfully the system unit is
searched last.
