In Windows the correct ABI is not even published.

E.g. we all do know that (with normal X86 32 bit windows) The Microsoft 
C compilers rely on the area to be be used for Threadvars is pointed to 
by a Selector register, while the docs say that this pointer needs to be 
fetched by a complex call.

That is why on that behalf fpc programs are slower than visual C programs.
