Here's what I ended up doing:

I kept that part and changed the prototype of the internal
do_spawn2() to match.

And the main reason to have them the same is that it also gives us
the new assert macros.  To maintain separate prototypes we'd now have
to maintain separate macros as well.

>It appears that win32 has a variant of do_spawn that does not wait for completion.  I am short of cycles to see what the impact of that being missing on VMS is right now.

I added Perl_do_spawn_nowait(), which is almost copy-and-paste from
the Win32 routine of the same name.
