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:

$ g77 -v

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,
