Someone can explain me this error?

[Alessio Igor Bogani]

Hi,

I'm trying to compile Gutsy git tree kernel with Ingo Molnar's Realtime
Preempt (-rt) patch.

I have this error but i don't understand what type of error it is.
Someone can explain me this error? Or suggest me how can resolve it?
What mean "error: expected declaration specifiers or ‘...’ before
‘mmu_gathers’" ?

Thanks in advance.

Ciao,
Alessio
