I am not convinced that the alpha version is still functional.  However,
it looks like HAVE_PUTENV should be defined in vax/xm-vms.h.  I will try
to find out whether putenv is available tomorrow.

As a general comment on this subject, the vax backend is functional
again for ultrix and bsd4.4.  Thus, I don't believe that the problems
in resurrecting the vax vms port would be very major if the alpha
port works.

Not if vax vms C has putenv.
