It seems that include/asm-x86/immediate.h in sched-devel.git causes

have seen no such problem with gcc-4.1. This is weird. It seems that
relaxing the constraint helps fixing this, but it's not clear whether
fixing the code or gcc-3.4 is the correct solution... here is the fix :

Fix immediate asm constraint for gcc 3 x86_64

It might make it compile, but it's completely *wrong* for the purpose intended.

It permits gcc to present the address in a register, for example, so there is no guarantee that you end up with an immediate.
