Note the GCC docs:
Assert that compilation takes place in a freestanding environment. This implies -fno-builtin. [...]
This will break a lot of code, since there are many thing that depend upon GCC builtin magic AFAICS.
(BTW, seems to be supported by GCC 3.3.0 too, because that manpage is packaged together with gcc-3.3.rpm (suse 9.x))
