In principle it looks ok, however:

I think it deserves a comment in exec.c saying why we do this - the prologue 
is reached via a direct jump, so must be placed close to the code segment.

Also, calling something .bss.code_gen, than placing it is .data is just asking 
for trouble :-) I suggest calling the section ".gen_code".

We probably want the same thing on sparc and ppc hosts. I guess they can be 
added as required though.
