You can read this thread on the fpc-pascal list: 
http://www.hu.freepascal.org/lists/fpc-pascal/2010-July/025939.html

Jonas has implemented a possibilty for external C threads to work, but 
you need to use a SVN FPC and you need to create at least one thread in 
FPC (it can terminate immediatly, it's just needed to initialise the 
threading subsystem). (And this fix is *nix only)
