Oops that's my bad.  autoconf handles this for me so I don't need that
#define.  I'll fix it.

That's a bug in the VMS changes; I'll fix it.

I'll fix this and two other places I found that use this syntax.  Man,
it's hard to write in C89 ...

I will fix this.  isblank() is well-defined as space or TAB so there's
really no reason to use this function.  I see it's part of C99 *sigh*.

This I can't answer; John Malmberg will have to give details.  However,
I see this in the README.VMS:

It looks to me like you started your test from GNV Bash?  There should
be a way to get the old behavior even when starting from bash.  A quick
read implies that enabling the GNV$MAKE_OLD_VMS setting may help.  Check
the README.VMS file for more details and verify.

Thanks for testing Hartmut!
