I agree to rename the template file. Including a template into the
release is something I do not suggest or support: there are no templates
in the released tarballs. As I said before, when suggesting the new name
for the template, I don't know or own the kit/release build. So someone
else needs to comment on this.

I agree.

I agree to have this for builds from a snapshot.

I disagree. I don't think that the template should go into the release.
The current procedure generating config.h-vms in the release build and
including it into the release is fine with me - and it seems to be
consistent with what is done for other operating systems/platforms.
But that's just my opinion. As said above, someone else should comment
on this.

That depends on 4.

I agree.

I don't mind the extra step to create config.h-vms, in case I have to
build from a snapshot. Actually, up to now I manually created/edited
that file. I also don't think that so many VMS users want to build from
such a snapshot. The latest release of VAX/VMS is from 2001. I didn't
think it was worth to try and/or test GNU make on that version. You are
trying and unfortunately running into a problem with the released
version of make which is fixed or doesn't show in a current snapshot of
the repository. But snapshots are and in my opinion should not be the
default for buildung GNU make.

I don't think that building the VMS version of GNU make by default uses
and has to use NFS. On the other hand, this sounds like a bug, which
someone in VMS/NFS engineering has to and probably will fix very soon,
as it affects VMS utilities. It is not GNU make related, so this doesn't
need to be handled, here - in my opinion.
