Hmm... I also noticed this problem, after following the UPDATING
instructions to get from 4.3-RC -> 5.0-CURRENT...
I managed to get the kernel to build successfully by hacking at the
linux_sysent.c file...
For some reason, the sys_exit line in linux_sysent.c in /usr/src gets
changed to something which breaks when it gets copied into /usr/obj...
(IIRC, I don't have both copies of the file available any more)
{ AS(sys_exit_args), (sy_call_t *)sys_exit }, /* 1 = exit */
was changed to something like
{ AS(rexit), (sy_call_t *)exit }, /* 1 = exit */
^^^^^ ^^^^
The 'underlined' (^^^) bits are definately right, I'm not sure about the
cast...
Any one have any ideas what would cause that?
(presumably linux_sysent.c is getting regenerated, incorrectly, somewhere?)
