These files were new in the 2.8 import (into the FSF branch) and cvs is stupid
enough to think my branch import want s the new files to end up in the trunk as well. Maybe cvs know how to do what I want, but I could not find it in the manpage

-! implementations. This file is the first thing linked into any executable.

-! This is a modified crt1.s by J.W.Hawtin <J.W.Hawtin@lboro.ac.uk> 15/8/96,
-! to allow program profiling, by calling monstartup on entry and _mcleanup
-! on exit

-
-! 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.
-! Initialize the first stack frame pointer in %ebp (the contents of which
-! are unspecified at process initialization).

- pushl $0x0

- movl %esp,%ebp
-
-! 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
-! so, register it with atexit() as the last thing to be run by
-! atexit().

- pushl $_mcleanup

-.L1:
-
-! Now check to see if we have an _DYNAMIC table, and if so then

-! 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!).
-
- movl 8(%ebp),%eax
- leal 16(%ebp,%eax,4),%edx
- movl %edx,_environ
-
-! 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.

-! Call _init(argc, argv, environ), _fpstart(argc, argv, environ), and
-! main(argc, argv, environ).
-

-
-! Pop the argc, argv, and environ arguments off the stack, push the
-! value returned from main(), and call exit().
