"Comment level 2 found" is only a warning, so I guess that you get some 
error message further. "Comment level 2 found" means that you triggered 
nested comments mechanism. In FPC in objfpc (and fpc and probably some 
others) modes, comments can be nested, which means that e.g.

   {$mode objfpc} { { } begin end.

*is not* a valid Pascal program. But in Delphi mode, e.g.

   {$mode delphi} { { } begin end.

*is* a valid program.

In other words: what you want is probably to just compile your unit in 
delphi mode, so that nested comments are off.
