>Description:
Hello,
I'm trying to build VirtualBox on 9.0-Release and get the following warning:

Error 1
=========>8=========SNAP=============
I checked /usr/src/sys/sys/smp.h and can see that mp_maxid is declared as
extern u_int. But I'm not sure if this is a compiler problem or just a wrong
declaration on line 124, for cpu_next(int i).
If it's changed to cpu_next(u_int i) it works, and virtualbox compiles and
works too.
Thanks.
KR,
Grimeton
>How-To-Repeat:
- Install 9.0-RELEASE
- Install src.txz from your fav. server
- Get VirtualBox 4.1.8 sources from www.virtualbox.org
- configure and build virtualbox and see the error message from above
>Fix:
One can change the delaration of cpu_next() to cpu_next(u_int i).
