- ! This code is placed at the beginning of the ELF executable and is the
- ! first thing that runs.

- ! On entry, the stack looks like this:
- !
- ! sp+.. NULL
- ! sp+8+(4*argc) env (X quads)
- ! sp+4+(4*argc) NULL
- ! sp+4 argv (argc quads)
- ! sp argc

- ! sp env
-

- lea ecx, (esp)(eax*4)

- push eax ! dummy, representing the return argument
