--- Comment #5 from Stas Sergeev <stsp at users dot sourceforge.net> ---
Basically this code calculates the distance
between "DPMI_return_from_realmode" and "DPMI_dummy_start",
and puts the result into a 16bit variable.
That explains the use of %ax. Its possible because
those funcs are in 16bit asm.
I think the gcc-generated asm code is perfectly fine here.
It optimized the 32bit calculus to 16bits.
