No, you misunderstand. I don't think Robert was proposing running VAX
code on Alpha (though I suppose that *is* an option).
There are two issues:
(1) Given a GCC port to a VMS target, there are some system-dependent
issues, such as filename syntax, that have to be addressed to port
GNAT to that system.
(2) There is a GCC port to VAX/VMS, but none currently to Alpha/VMS.
The latter port is neither trivial nor exceedingly complex. So far no
one has comitted to doing it but someone (you know who you are!) told
me at Tri-Ada that he wanted to do it.
So, GNAT for VAX/VMS requires only (1) above to be done, but GNAT
for Alpha/VMS requires both (1) and (2). Note that when (1) is done,
that part will also be usable for Alpha/VMS and so once that GCC
port is done, GNAT would then run without any further work.
