Not reading manuals?  :-)

http://www.freepascal.org/docs-html/prog/progse5.html#x121-1210002.2

so it is FPC_FULLVERSION, not FPCFULLVERSION

from

http://delphi.wikia.com/wiki/FreePascal_detection_and_versioning

a typical usage:

{$if FPC_FULLVERSION> 20204} 
   // means greater than 2.2.4 here
 {$ifndef}
