! Start creating the initial frame by pushing a NULL value for the return
! address of the initial frame, and mark the end of the stack frame chain
! (the innermost stack frame) with a NULL value, per page 3-32 of the ABI.

! As specified per page 3-32 of the ABI, %edx contains a function 
! pointer that should be registered with atexit(), for proper
! shared object termination.  Just push it onto the stack for now
! to preserve it.  We want to register _cleanup() first.

	pushl	%edx

! Check to see if there is an _cleanup() function linked in, and if

! Compute the address of the environment vector on the stack and load
! it into the global variable _environ.  Currently argc is at 8 off
! the frame pointer.  Fetch the argument count into %eax, scale by the
! size of each arg (4 bytes) and compute the address of the environment
! vector which is 16 bytes (the two zero words we pushed, plus argc,
! plus the null word terminating the arg vector) further up the stack,
! off the frame pointer (whew!).

! Push the environment vector pointer, the argument vector pointer,
! and the argument count on to the stack to set up the arguments
! for _init(), _fpstart(), and main().  Note that the environment
! vector pointer and the arg count were previously loaded into
! %edx and %eax respectively.  The only new value we need to compute
! is the argument vector pointer, which is at a fixed address off
! the initial frame pointer.
