I realise that, and that the implementation would probably be quite
difficult.  On the other hand, IIRC a compiler is required to say that a
program is too complex for it if that is the case; from a user's point
of view this is something similar.  I was just wondering if folks
thought it would be a good idea.  :-|

I suppose it is a quality-of-implementation issue.

Right, it's always "the processor".

This is more than I need.  Presumably, the constructor of the processor
knows, or can suspect, if something in the format of the results of
compilation has changed, and could write the compiler version into those
results, to be checked by whatever version of the compiler wants to USE
those results.

No problem; your opinion and expertise are respected here!

(By the way, apologies for any confusion caused by me posting my
original problem in comp.lang.fortran and on the comp-fortran-90 mailing
list.  I was thinking that (were it in fact some subtlety I had missed)
that the latter might have more experts, while in the former I might be
more likely to find someone with the same or a similar compiler with
whom to compare results.)
