I beg to differ. 

------------------------------------------------------------------------
test()
{
  if (0)
    some_func();
}
------------------------------------------------------------------------

yields: (gcc -O2 -S test.c)

------------------------------------------------------------------------
        .file   "test.c"
        .version        "01.01"
gcc2_compiled.:
.text
        .align 4
.globl test
        .type    test,@function
test:
        pushl %ebp
        movl %esp,%ebp
        leave
        ret
.Lfe1:
        .size    test,.Lfe1-test
        .ident  "GCC: (GNU) 2.95.2 20000116 (Debian GNU/Linux)"
------------------------------------------------------------------------

Bye,
Sebastian
