[jhb]

Summary

• Use ia32_freebsd4_* instead of ia32_*4.
• Use ia32_o* instead of ia32_*3.

I suspect these ifdefs in the header can be removed.

sys/amd64/ia32/ia32_signal.c

Why osigframe? Is there a reason for that naming convetion?

[brooks]

I think this is right.

@imp COMPAT_43 syscalls get named o<syscall> so this follows that convention. The "3" suffix is weird.

Because the rest of things for COMPAT_43 use the 'o' prefix including syscalls, etc. These aren't FreeBSD 3.x things, but BSD43, so the 3 suffix is weird.
