The FAQ clearly says in section 18.9 that the `__dpmi' functions should 
be used for interrupt handlers written in assembly, while the `_go32_' 
functions are for handlers written in C.  The `__dpmi' variety are 
bare-bones wrappers around the DPMI calls, while `_go32' functions set up 
the stack, push registers and do other things to convert a C function 
into an interrupt handler.
