Dear Steven G. Johnson, you wrote on Yesterday:

Completely agreed. I'd be happy if the same was true for g77.

I haven't made that experience yet (both produce 32 bit code by default on
our machines). And I thought that we partly solve these problems with
the NAME_MANGLING macro, right - ?

Anyway, putting f77 first was just a suggestion, and I can easily go with
your arguments.
Another point though (practical experience): The SGI, Sun, AIX machines
at our site often have poorly administered GNU software installed that
is outdated or sometimes even doesn't work at all, whereas the
vendor software is updated on a regular basis. This may result in autoconf
finding a GNU compiler, trying to use it, and fail.
The Linux systems are the only ones where the GNU software is always
cutting edge.
I don't know whether that is typical, but it might be an (albeit
poor) argument in favour of f77.
Regards,
Martin
