When building the 464.h264ref SPEC CPU2006 benchmark with dragonegg-2.7 at -O2
(with gcc-4.5.0), I'm seeing these error messages at link time:

ratectl.o: In function `rc_init_pict':
ratectl.c:(.text+0xcab): undefined reference to `__builtin_lfloor'
ratectl.c:(.text+0xce7): undefined reference to `__builtin_lfloor'
ratectl.c:(.text+0xe6d): undefined reference to `__builtin_lfloor'
ratectl.c:(.text+0xea9): undefined reference to `__builtin_lfloor'
ratectl.c:(.text+0xef3): undefined reference to `__builtin_lfloor'

Duncan informed me that he was already aware of this problem, but hadn't
adressed it yet...
