Notice the in the following a completely different result from gcc.  
Your implementation-specific question is not topical for any of comp.lang.c or
comp.lang.c++.  I have removed them from the follow-ups.

Your implementation-specific question is also invocation-specific.

        .file   "a.c"
gcc2_compiled.:
___gnu_compiled_c:
.text
        .p2align 2
.globl _main
_main:
        pushl %ebp
        movl %esp,%ebp
        movl %ebp,%esp
        popl %ebp
        ret
