g77 -v doesn't work anymore.

Zack,

g77 -v used to give useful information about the installed version and
the version(s) of the run-time libraries, like so:

That doesn't work anymore:

Somehow, tradcpp manages to get three /dev/null's out of the specs file
- even though only two are there (f/lang-specs.h).

Why is this ?

Thanks in advance,

The third /dev/null comes from the %i in %(cpp_options).

I don't like this feature of g77, I think it's unnecessary
complexity.  But if you must have it, just pull out one of the
/dev/nulls.

Thanks, I'll do that.

We've used this feature in the past to get people to check if they had
an installation problem (a common one was to pick up a libf2c built by
the f2c distribution - note that until recently, most Linux
distributions came with f2c and _not_ g77).  It might be that this isn't
necessary anymore.

But as long as it doesn't break or inhibit anything else, I'd like to
keep it.
