The existing port of Bash for VMS claims to be 1.4.8, which as near as I
can tell must be based on 1.4.7, as I do not see a 1.4.8 in the download
section.
What they did to work around that VMS does not have a fork() call, is to:
Make a copy of several global variables and structures.
Set the global variables to point to the copy.
set a stack local structure to point to the original values.
And then at a later point where the child processes has exited:
Set the global variables to point to the original structures
Dispose of the copy.
Since then, the structure of Bash and the global variables has changed a
bit.
So what I am trying to find is where in Bash 4.2 that I should be
putting the save/restore, what variables need to be
copied/saved/restored, and what the best routines to do that.
And where I can just set a flag to avoid the fork() operation all together.
