These errors suggest you are not compiling that unit in FPC mode. If you 
use the top level Makefile in the fpcsrc directory, it will compile the 
packages directory with RELEASE=1, which in turn causes -n to be added 
to the FPC command line options so that it ignores any default 
(.)fpc.cfg files (that may otherwise contain -Mdelphi or so). The 
default compiler mode in FPC (including 3.0) is plain FPC mode.
