The alpha/xm-vms.h port hardcodes #define HAVE_PUTENV, so as currently
written, gcc.c won't define putenv() at all.  Somehow its already
working there without the NOP.

My understanding from previous posts is that the vax vms port is
broken and whoever wants to resurrect it will have to start with the
alpha one (or from scratch) anyway.

With this in mind, do you still object?
