There is librarian support, as can be seen in default.c where AR is set
to "library/obj" and ARFLAGS to "/replace". It is known that the VMS
librarian and Unix ar behave differently. For example, librarian expects
an object library to exist for the "/replace" command while ar's "r"
command just creates a non-existing archive. So there is "some" support.
Maybe the feature shouldn't be set.

As I understand, to run the tests you need gnv. So you are using gnv and
bash and not "plain" VMS. However, for VMS this is not really surprising:
$ write sys$output f$message(%x1086109c)
%LIBRAR-F-OPENIN, error opening !AS as input

If you create the archive/library
  $ libr/cre libxx.a
given the object a1.o and a rule like
  libxx.a(a1.o): a1.o
will result in a
  library/obj /replace libxx.a a1.o
and as said above, replace will not create a library:
  $ delete libxx.a;
  $ library/obj /replace libxx.a a1.o
  %LIBRAR-F-OPENIN, error opening USR_ODS5:[BECKER_H.X]LIBXX.A; as input
  -RMS-E-FNF, file not found
  $

Yes, argv[0] in VMS is something like
  eagle$dqa0:[alpha_root.gnv.make]make.exe;1

This looks like a simple exit with MAKE_TROUBLE, which for VMS is
#defined to 2. It would be nice to have VMS error messages or at least
VMS compatible error messages, here.
