Wouldn't it make sense to suppress the check and creation of the
libraries? That is, replace
  "if f$$search(\"address@hidden") .eqs. ..."
  "@if f$$search(\"address@hidden") .eqs. ..."

Adding other VMS library types is OK with me. There is one more:
shareable image libarary.

I agree to remove them.

I don't think that VMS should include all the Posix/Unix extensions. The
Posix subsystem for VMS (had it's own Posix compliant make and) is gone
and GNV is not VMS. I know, I said this before, I think for Gnu make,
GNV should be separated from VMS.

Another question: how should these new pattern rules for non-object
libraries be used?

For objects one can use
  all: o.olb(o)
  all: o.olb(o.obj)

For help files one can use
  all: h.hlp(h)
but not
  all: h.hlp(h.hlp)
  all: h.hlp(h)
doesn't work if there are h.h and h.hlp in the same directory.

  all: o(o)
  all: o(o.obj)
  all: h(h)
  all: h(h.hlp)
expected to work? The second rule worked with the old VMS make. With
the new code, always a new library is created. It may break existing
makefiles, so it needs to be documented.

And a comment: on OpenVMS/I64 CXXLINK is not required and not recommended.

And a side note: in the features_archives.gdiff there is a trailing dot
in the filename which prohibits patching the file without manual
specifying the correct filename.
