I'm talking about benefits for the process (developers, testers) and
the result (end users, dogs eating own food :).

text data bss dec hex filename
5159478 1005139 406784 6571401 644589 linux-2.6.23-rc4.org/vmlinux
5131822 996090 401439 6529351 63a147 linux-2.6.23-rc4.gc/vmlinux

Are this numbers show embedded target? I think no. Also time factor of
*10* can be spent more productively reviewing actual code of parts, that
are going to be embedded, no?

OK, thank you very much. Now, describe what problem you are talking
about, please. I see non.
