The compiler doesn't say `fatal error' at all as far as I know.  If
the error message in this situation isn't clear, or the part of the
g77 manual to which it refers isn't clear, could you suggest how we
could improve it?  Thanks.

[At least one (rather reliable) proprietary compiler I know of behaves
essentially the same as g77 in this context.]
