cvsouped current last night and compiled world on our 4 CPU HP Netserver

First of all, 'make depend' gives the following:
In file included from ../../i386/isa/icu.h:50,
                 from ../../i386/eisa/eisaconf.c:45:

Which I easily ignored :) (didn't have time to examine it closely.)

Then I got some errors from time.h:
/usr/include/time.h:95: parse error before `struct'
/usr/include/time.h:96: parse error before `struct'
/usr/include/time.h:97: parse error before `const'
/usr/include/time.h:103: warning: `struct timespec' declared inside parameter 
list
/usr/include/time.h:103: warning: its scope is only this definition or 
declaration,
/usr/include/time.h:103: warning: which is probably not what you want.

Got rid of those.

After that, make world worked, got a new kernel, reboot, all 4 CPUs 
starting and everything looks just fine.

Conclusion: SMP_AUTOSTART works on 4 CPUs
