[Simh] Unable to build on NetBSD

[Clem Cole]

Cory,

Hmm, the PWD 3.0/System V later Posix shm(2) functions I would have
expected NetBSD to have picked up by now I agree.  But no matter, I believe
you can use the mmap(2) mechanism if you want  shared memory in BSD post
4.4.  I wrote some code for a book chapter using it a long time ago.  Get a
copy of Rago's update to Steven's APUE and I believe you find an example if
not just google for mmap(2) examples.
