Which one is that? The 7.1 release?
The version you installed in virtual box is 7.1 as well?

Are you sure you did not modify MYKERNEL in between?

This is the error: the declaration of ucontext_t does not create a structure
of the expected size.
This means: something is wrong in your compilation environment. Either the
wrong headers are used (or headers for the wrong architecture), or the build
system is broken.
The latte is possible, not very many people compile kernels only, and in
the usual cross-build setup, everything is handled automatically.
However, what you did (and what is described in the guide) should work - so
let us find out what went wrong where.
I tried it on a system running NetBSD/i386 from the netbsd-7 branch with
an i386 GENERIC copied to MYKERNEL and it works for me.
