Of course this is why I started the thread. The C compilers seem to work 
more efficient on that behalf and thus it might be viable to improve 
FPC. To do that the details of how segment registers are used with the 
X86/32 architecture in Linux and Windows needs to be thoroughly 
understood. (In fact I still don't know how the compiler should 
construct a pointer to a threadvar in Linux).
