Dear all, a quick question... While trying to compile the latest busybox git version using clang 3.2-2+b1, I quickly discovered a nested function in the code... apparently the only one. ;-) See below.
My question is... does anyone know how much bigger (approximately) the
code is without such a nested function?
Thanks in advance.
Cheers! :-)
Ben.

- auto action* alloc_action(int sizeof_struct, action_fp f);
- action* alloc_action(int sizeof_struct, action_fp f)
- {
- action *ap;
- appp[cur_group] = xrealloc(appp[cur_group], (cur_action+2) *
sizeof(*appp));
- appp[cur_group][cur_action++] = ap = xzalloc(sizeof_struct);
- appp[cur_group][cur_action] = NULL;
- ap->f = f;
- IF_FEATURE_FIND_NOT( ap->invert = invert_flag; )
- IF_FEATURE_FIND_NOT( invert_flag = 0; )
- return ap;
- }
