[Bug c/17830] New: Gcc 3.4.x can't compile linux 2.4 kernels

[ant_diaz at teleline dot es]

Neither Gcc 3.4.0 nor 3.4.2 can compile linux 2.4 kernels (tested with
linux 2.4.26 and 2.4.27). Gcc 3.3.3.and 3.3.4 work fine.

It gives several errors like this:
sched.c:213: error: conflicting types for 'reschedule_idle'
sched.c:210: error: previous declaration of 'reschedule_idle' was here

The offending lines are these:
sched.c:210: static FASTCALL(void reschedule_idle(struct task_struct * p));
sched.c:213: static void reschedule_idle(struct task_struct * p)

The 2.4.26 kernel can be compliled (with tons of warnings) applying this
patch to include/linux/kernel.h:
